Re-Stocked, White, Some with Butterscotch Backs, 3/8" River Shell 2-Hole 9mm Button, Pack of 75 # LP-68/75
Most of these Freshwater Shell buttons are true white on both sides. Some of the backs have a bit of natural butterscotch/tan shell color as you can see. There will be a few with a bit of peach on both sides. But it also depends on the light; sometimes they are pure white. They are about 1/16" thick and the hole is about 1.5mm. Just enough of the natural shell's glow comes through to create a lovely sheen and iridescence. (Clearly these are not plastic buttons!) None are grayish or greenish; that's a photography/lighting/iridescence issue. Satiny, thick, durable, smooth and a bit shiny. Some may be a bit rustic.
You'll get about 75-80 buttons, for $7.25. 3/8" - small.
