Koogel Three Piece Silicone Box Mold Set For Resin Casting. This great set of silicone molds comes with three different shaped molds. One Cylinder Shaped Mold, One Cuboid Shaped Mold and One Hexagon Shaped Mold. They all measure approximately 3"x3". This set also includes a Flash Powder Pack in 12 beautiful colors! The molds are very good quality and can be used many many times! I love getting products from Koogel because I can always count on them to be reliable and very well made!
