Look how beautiful they turned out. She meant to purchase the bottlecap cameos (which are low dome resin cameos) to use with these bottlecaps but accidently purchased the buttons version instead. And whoa-la, what a happy little accident. The bottlecap cameos are 25mm in measurement. And the 1 inch buttons are a little bit smaller (about 1 to 2 mm smaller). Even though they are known standard in the industry as 1 inch. 1 inch is about 23-24mm.
