Choose a zipper or a frame
SN80 uses a top zipper, while SN81 and SN83 have metal frames with clasp closures. Pick the zip-pouch shape if you prefer a continuous opening along the top.
For size, compare SN80 at 6 in x 4.5 in with SN81 at 6 in x 4 in or SN83 at 3.5 in x 3 in. These are different formats, so check the measurements as well as the design.
