The plastic mold consists of two parts. A board with a carved pattern and a frame.

Procedure: 1. First, pour the chocolate onto the board, pull it so that the chocolate remains only in the pattern. 2. Place the frame so that it fits precisely in shape on the carved pattern. Pour again with chocolate, but of a different color, align with the frame, and let it harden. 3. After hardening, remove the frame and carefully also the board.

It is also possible to make a box from solid surfaces.
