This is the perfect size for me to handle while I am doing my resin molds... I love being able to make my own molds so that I can custom make something for my family as gifts, or for a craft show. Everyone is into crafting with resin now so being able to make my own molds for resin makes me a step ahead of the game. The molds come out perfect and rubbery, easy to take the resin article out of, and holds up well. There are directions on the page where you buy this to help you through the steps of making your own mold. This is absolutely perfect!
