Easy magnetic building system for small balsa models. Make perfectly perpendicular joints every time!

Each cube features a series of slots and grooves for 1/8", 1/16", and 1/32" wood. Holds sticks or sheet perfectly vertical while glue dries. Also excellent for holding larger structures square using the flat sides. The round holes are a perfect fit for the 5/16" x 1/8" magnets sold at Harbor Freight Tools. Each cube also features holes for pinning to a non-magnetic building board.

Please note that the plastic is porous, so care must be taken to prevent gluing parts to the cubes. Coating the cubes with automotive wax or WBPU is recommended.
