These seem to be very popular and they are made from acrylic with a lobster clasp and a pom pom. The whole alphabet is available but colors can not be promised. It depends on if we have the correct supplies in stock. Wishes can be made through the website and we will do our best to make it happen. Usually we put glitter acrylic as the backing and the solid color as the initial but if you want it differently please mention it in the comment section
