Makedo SCRUs

Makedo is the most open-ended toy construction system ever because the reusable tools work with cardboard; a universally available, free and unlimited building block. Each SCRU connects up to six layers of corrugated cardboard. Punch a hole through the material using the MINI-TOOL, Insert the SCRU into the socket on the MINI-TOOL, and then with a few quick turns the cardboard will be securely joined.
