These are called flat backs. They are made of PVC plastic. They feel like a type of rubber, but it is really type of plastic made from vinyl. These flat backs are very light weight and are perfect for so many DIY projects including making earrings, gluing to flat focal beads, gluing to cell phone cases, gluing to bags or purses, and gluing to barrettes. These are all equestrian but we have many different designs too. These are not focals. They are much thinner.
