The Grain Maker Set consists of four parts.
Cartridge: The cartridge consists of two chambers with reactive basic components.
Piston: The piston is used for pressing the two substances through the mixing tip.
Mixing Tip: The mixing tip mixes the two reactive components when pressed out of the cartridge.
Plastic Foil: The plastic foil is used to make the reverse side of the grain copy smooth. With the Grain Maker Set two grain copies can be produced. Grains can be repaired on vinyl and pigmented leathers, but not on porous or absorbing leathers.
