The IOD Grapes 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 is great for creating a flat back to your casting.

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.
