Approximate measurements:
Small--1/8" tall by 3/8" wide Mathematically this works out to be 2g, but we recommend being 0g 1-5/16" tall 6.5grams
Large--3/16" tall by 7/16" wide Mathematically this works out to be 0g, but we recommend being 00g 1-9/16" tall
Insertion gap on both sizes measures 1/8" (3mm).
