I ordered 2 magnetic putty sets for Christmas gifts for friends. One of them was round on Christmas day and he opened it there and then and loved it. It was kind of creepy how it works and since the magnet that came with it was powerful.

The combination of the strong magnetic cube and the putty was very enjoyable; the magnet would sink into the putty and bond as if the putty was magnetic (which of course was magnetic). Overall though I had plenty of fun with these magnets.
