Set the pieces on a clean preparation surface with cooked rice and a separate plate nearby. Fill evenly and apply gentle pressure, then release the rice carefully rather than flexing or scraping the mold.

Product Overview

The Nishiki 150780 is the larger two-piece triangular rice-mold set. White polypropylene pieces shape rounded triangular onigiri portions, with an 80 × 145 × 55 mm overall product format.

After shaping: clean, dry and store

Recommended care: hand-wash with mild detergent and a soft sponge, rinse well, and dry all pieces before storage. Clean rice from the recesses without knives or abrasive tools. Keep away from direct heat.

Wash before the first use and after each preparation session. Check the edges and pressing surfaces before use; stop using a piece if it cracks, chips or becomes distorted. Food, rice paddles, mats and serving dishes are sold separately.

150780 original product form

A larger rounded-triangle format

The paired triangular pieces have softly rounded corners and recessed center details. Choose this larger model when you prefer its size over the compact 150285, while retaining the same general onigiri outline.

The larger format still uses a compact pair of molding pieces, rather than a long multi-cavity tray. Keep the pieces aligned during preparation and leave a clear landing area for each shaped portion.

Prepare the rice and pieces together

Set the pieces on a clean preparation surface with cooked rice and a separate plate nearby. Fill evenly and apply gentle pressure, then release the rice carefully rather than flexing or scraping the mold.

Keep the mold and serving area separate from raw ingredients. Add any toppings only when the rice is ready to serve, and use a clean plate for the finished portions.

Compare the two triangular sizes

The smaller 150285 has a 72 × 135 × 50 mm product format. These are mold dimensions, not a promised portion weight; the finished rice depends on how the mold is filled and pressed.

Recommended care: hand-wash with mild detergent and a soft sponge, rinse well, and dry all pieces before storage. Clean rice from the recesses without knives or abrasive tools. Keep away from direct heat.
