Abigail P. ★★★★★

My kids fought over this thing all weekend, which I did not expect from a wooden puzzle. The seven pieces are sanded smooth and fit tight enough that the cube holds together when you pick it up.

Isabella U. ★★★★★

I picked this up for myself, honestly, and ended up spending a whole evening trying the 240 different ways to build the cube. The seven wood pieces are sanded smooth with no splinters, and they fit together tightly enough that the finished cube holds its shape on the shelf.

Sofia ★★★★★

My 8-year-old has been obsessed with this since it arrived, and I love that there are 240 different ways to fit the seven pieces into a cube, so he never gets bored. The wood has a nice weight to it and the edges are sanded well, no splinters after weeks of daily use.
