The Titan puzzle by Felix Ure is a deceptively hard puzzle.
A simple looking brass sphere, the aim is to open it. However after playing around you will find this is not as simple as it first seems.
Machined in the UK from solid brass, Titan measures 50mm in diameter and weighs a hefty 515g.
The brass is left unfinished which means it will slowly patinate and darken with use.
It comes in a beautiful presentation box.
