This mold was crafted from a 7" tall beer bottle. It is made from a semi-translucent food grade silicone. This design allows you to create a bottle that you can see as you pour. Can be used with many mediums such as isomalt, chocolate, and hard candy. Very easy to use. Strap 3 rubber bands around the mold. Fill 1/3 of the way with your favorite hot sugar. Rotate the mold until sugar has begun to set. Stand upright and allow excess to drain. Let it cool completely. Demold. What a great bottle for an ice bucket cake with bottles in it. This is the original "CakeStructure" bottle mold and is being produced with permission by Sugar Delites.
