This silicone mould in the shape of a heart size 100 x 80 x 10 mm is ideal for casting crystal resin or Jesmonite and can be used repeatedly. Casts from this mould will serve as beautiful decorations or as functional accessories, if you use the cast heart, for example, as a coaster. To prolong the service life of the mould, we recommend applying a separator to the mould before the start of the casting process.
