Stampo in silicone per pasta polimerica e paste di metallo - Farfalle

the internal molds are too thin, it hurts to let in the color especially in the frame as you can see in the picture, some molds have internal defects, the molds aren't well defined, it was a test and I don't like it, I will not use it because I,personally,I like the cabochons of greater thickness,so for those who think the same as me I don't recommend it,
I'm sorry for the store but I was very disappointed with this purchase.
I expected the most resistant cabochons but they are very fragile and thin, they break easily regardless of the resin you use
