Two-piece silicone mould for casting a box in the shape of a double heart with a lid size 160 x 100 x 45 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. To prolong the service life of the mould, we recommend applying a separator to the mould before the start of the casting process.
