Vintage Soda Bottle Caps, for Jewelry Making, measuring approx. 32mm. Sold in packages of fifty (50) pieces. These bottle caps are not as fancy or unique as our 6 packs, however they are great for practicing on. If you have ever wanted to try resin or making a pair of bottle cap earrings or "beering" these are the perfect way to start. Such a fun and whimsical project! They work really well with our turtle back bezels. https://www.bsueboutiques.com/brass-bezel-turtle-back-jewelry-supplies-01142-p/bez01142.htm
