The IOD Frames mould includes information right on the mould showing the amount of clay or resin needed to make that mould to reduce product waste.
The micro rim technology you love on the other other IOD moulds, allowing for a smooth back of your casting, is also found in the Trimming III mould.
In addition to using with your favorite filler (clay, resin, and more), the IOD moulds are also food safe. NOTE: if using a mould for food you should not use for any other non-food purpose.
