Allard's Think © Sticks is a cylindrical burr set. The 15 pieces within the tin create a total of 12 different nine piece burr assemblies (and a few six piece burrs too.)

The pieces have a nice heft to them, each piece having a 9.5mm diameter and being milled from solid brass. The puzzle is presented in a tin and comes with a plastic lid to enable resealing once you've pulled that ring pull.
