What does the ERS order data show?
Among qualifying ERS orders, the median fulfilled order is 16,000 pairs, the median interval between repeat orders is 35 days, and 78% of fulfilled orders were repeat orders.
Those are purchasing observations inside ERS records. They are not national market estimates, consumption measurements or recommended order rules. The sections below show the denominator, method and limitation attached to every answer.
Context, comparison, planning questions and transparent aggregate evidence.
National market share, a depletion promise, causal claims or a substitute for a restaurant’s own demand.
Study boundary
What evidence is included?
The study includes 8,650 fulfilled orders, representing 203,817,600 pairs supplied across 1,934 restaurant locations.
| Unit | Working definition | Not equivalent to |
|---|---|---|
| Qualifying order | A fulfilled custom-chopstick order retained after excluding cancellations, fully refunded lines, non-product fees, proofs and samples. | A restaurant, meal, visit or diner |
| Fulfilled quantity in pairs | The eligible fulfilled quantity stated as chopstick pairs in this edition. | A pair confirmed as consumed |
| Resolved location | A ship-to restaurant establishment supported by the customer and transaction records. | A unique corporate customer or representative U.S. restaurant |
| First-observed order | The earliest qualifying order visible for a resolved restaurant location inside the study period. | That location’s certain first-ever custom-chopstick purchase |
| Repeat order | A later qualifying order at the same resolved restaurant location. | Customer retention, exclusivity or proof that ERS supplied every intervening purchase |

Order size
How large are fulfilled custom-chopstick orders?
The median is 16,000 pairs. The middle 50% spans 11,200–28,800 pairs, so one number cannot describe the range restaurants purchase.

Reorder behavior
What does the order history show about repeat ordering?
78% of fulfilled orders were repeat orders. The median interval between repeat orders was 35 days.
| Question | Result | Interpretation boundary | Details |

Product-format mix
Which chopstick format accounts for more ERS-purchased pairs?
Within mapped ERS pair volume, Bamboo Twin accounts for 62% and Bamboo Tenso for 38%. This is ERS customer mix, not U.S. market share or a quality ranking.
| Mapped format | Share of qualifying fulfilled pairs | Denominator | Finding |
|---|---|---|---|
| Bamboo Twin | 62% | n=203,817,600 pairs supplied; 126,366,400 Bamboo Twin pairs | View finding |
| Bamboo Tenso | 38% | n=203,817,600 pairs supplied; 77,451,200 Bamboo Tenso pairs | View finding |

Artwork continuity
How often did repeat orders use unchanged approved artwork?
Across all repeat orders in the Benchmark population, 94% reused unchanged artwork.
What “unchanged” should mean
The later order must connect to the same approved artwork revision identity. A renamed file alone does not prove a change, and a visually similar file does not prove continuity.
Basis: n=6,716 repeat orders; 6,313 unchanged · 2002–2026
| Measure | Result | Population / interpretation |
|---|---|---|
| Repeat orders using unchanged artwork | 94% | n=6,716 repeat orders; 6,313 unchanged |
| Eligible proof projects | 2,347 proof projects | Projects with linkable version history and known disposition |
| Initial proof approved without a customer-requested revision | 68% | n=2,347 proof projects; 1,596 approved without customer-requested revision |
| Revision rounds when a project required revision | 1 median revision round | n=751 revision-bearing proof projects; zero-revision projects excluded |

Inventory context
What can the purchase history say about inventory coverage?
For the defined stable-cycle subset, median implied purchasing is 10,700 pairs per month. At that rate, the current 11,200 pairs program minimum represents 32 days of arithmetic coverage.
| Measure | Result | Valid use | Not supported |
|---|---|---|---|
| Stable-cycle implied purchasing | 10,700 pairs per month | Historical context for a predefined subset. | A restaurant consumption default. |
| MOQ coverage at that median | 32 days | Transparent arithmetic using the current ERS minimum and stable-cycle purchasing median. | A guaranteed depletion date or reorder recommendation. |

Seasonality
Does qualifying purchasing change through the year?
The normalized index is highest in October 1.17 and lowest in January 0.84. These are purchasing signals in ERS records, not forecasts of restaurant demand.
| Index point | Value | Alternative explanations to test |
|---|---|---|
| Reported high | October 1.17 | Customer acquisition, campaign purchasing, price change, delayed fulfillment or a large multi-location order. |
| Normalized monthly mean | 1.00 | The reference level, not a predicted month or restaurant baseline. |
| Reported low | January 0.84 | Short calendar, stock carryover, supply constraint or shifted fulfillment timing. |

Methodology
How did ERS measure the Benchmark?
ERS completed this edition from qualifying order, location, artwork and proof records through the published observation cutoff. Every finding retains its unit, population, denominator, period and interpretation limit.
- 01
Fulfilled-order population
ERS retained qualifying fulfilled custom-chopstick orders. Cancellations, fully refunded lines, non-product fees, proofs and samples were excluded.
- 02
Quantity stated in pairs
Every eligible fulfilled quantity was stated in chopstick pairs, giving order-size and pair-volume findings one consistent unit. Line-level product mappings are not part of the public report.
- 03
Physical-location sequence
Customer and ship-to history was resolved to restaurant locations. The earliest eligible order at each location was classified as first-observed; later eligible orders at that location were classified as repeat orders.
- 04
Chronology and artwork continuity
Repeat intervals are calendar days between consecutive eligible orders at the same location. Artwork was unchanged only when an order used the same approved revision identity as the immediately preceding order.
- 05
Finding-specific denominators
Order statistics count orders, product mix counts fulfilled pairs, stable-cycle context counts qualifying locations and proof outcomes count eligible proof projects. Each public finding shows its applicable basis.
- 06
Edition and privacy boundary
The edition reports aggregate results through the observation cutoff. Restaurant, order, artwork and proof records remain outside the public storefront.
Order and location denominators
- Order distribution: n=8,650 orders.
- First and repeat order size: n=1,934 first-observed location orders; n=6,716 repeat orders.
- Repeat-order share: n=8,650 fulfilled orders; 6,716 classified as repeat orders. Order-weighted share; not customer retention or a location cohort rate.
- Stable-cycle context: n=438 restaurant locations. Implied purchasing is not measured diner consumption and can omit other suppliers or inventory changes.
Pair, artwork and proof denominators
- Product mix: n=203,817,600 pairs supplied; 126,366,400 Bamboo Twin pairs; n=203,817,600 pairs supplied; 77,451,200 Bamboo Tenso pairs.
- Artwork continuity: n=6,716 repeat orders; 6,313 unchanged. Continuity is based on approved revision identity; file renaming alone is not treated as an artwork change.
- Initial-proof approval: n=2,347 proof projects; 1,596 approved without customer-requested revision.
- Revision-round median: n=751 revision-bearing proof projects. This denominator excludes the 1,596 projects approved on the initial proof.
Release checks and privacy
- Reported order and pair totals were reconciled to edition 2026.1.
- Each percentage was verified from its integer numerator and denominator before display rounding.
- Visible findings, semantic tables and structured data were checked against the same approved aggregate definitions.
- The public release contains aggregate findings only; customer names, negotiated prices and record-level artwork remain non-public.
Interpretation boundaries
What can the Benchmark not establish?
The data can describe qualifying ERS purchasing. It cannot independently establish national restaurant behavior, guest consumption, causation, loyalty or the correct order for a specific operation.
| When the Benchmark says | It means | It does not mean |
|---|---|---|
| ERS customer population | Transactions meeting the published eligibility rules. | A probability sample of all U.S. restaurants. |
| Pairs purchased | Eligible fulfilled quantities stated in chopstick pairs in the approved edition. | Pairs consumed, meals served or guests supplied. |
| First-observed | Earliest qualifying order visible in the analysis window. | Certain first-ever purchase. |
| Repeat order | A later qualifying ERS transaction was observed for the same resolved location. | Loyalty, exclusivity, satisfaction or the absence of other suppliers. |
| Difference between groups | A descriptive association in the records. | Proof that sequence, format, geography or time caused the difference. |
| Aggregate planning context | A benchmark after the operator calculates its own demand. | A prescription, lead-time promise or depletion date. |
Correction policy: if a source or calculation correction materially changes a finding, ERS updates the value, edition, published tables and correction history together.
