These silicone molds are well made & perfect for shakers. This particular mold is approx. 48x42mm & 10mm depth. The mold itself is 1 part & is designed for the shaker portion to be sealed by clear plastic film (NOT INCLUDED) onto which you would put an additional layer of UV resin. If you are working with polymer clay, you can bake your clay right in the mold, this will allow you to release the molds without distorting the image.
