comes 18 pieces to each sheet that you purchase. The individual stone shims themselves are 2" by 4" in size and are made from a hard plastic material. They're the perfect item to have around when you need to split a stone that you're working with into a particular size. Each shim can be used multiple times (approximately four) before it will need to be replaced with another one.
