Two Brick Red Toggles, Old Flower Pot Buttons 2" #BCH-37 Animals + Birds + Bugs It was a technique usedLarge sea buttons are from ocean tumbled old brick; sleek and opaque, not shiny, 2" long. They're from pieces of old broken terra cotta flower pots, floating in the ocean for a very long time and smoothed to this shape and size naturally. Gathered recently and drilled with two holes to become buttons. Yours will be the exact ones shown, both in a set, so order "1".
