    This is the easiest molding material I have ever used. The molds are very flexible but very sturdy as well. I wish I could find some forms to use as building my own is not cutting it. Thanks for a great product.

    Great stuff. It can handle all the rough handling I put it through without losing its shape. And the mostly clear frosted glass look is great for being sure that I have enough coverage and that everything is being covered without hidden bubbles.

    I love this silicone, it is easy to work with. My molds turn out beautiful. I love that I can use it with food and not just epoxy. My creations are lovely and detailed and My customer love their molds too. I am so glad I found this silicone.
