Safecracker 40

A one-piece, handcrafted wooden math and logic brain teaser for teens and adults. Made from maple with a cherry finish, it delivers a repeatable challenge in a pocketable form.

Goal: Align the wheels so each of the 16 columns equals 40 at the same time.

Size: 4.4″ x 4.4″ x 0.75″.   Deep laser engraved numbers and text will not fade.
