Brass Monkey Three. Just two rings engraved on the end of each piece differentiates it from Brass Monkey One (no rings), Brass Monkey Two (one ring) and Brass Monkey Four (a deeper central hole) which are both available in our store. This puzzle is a brand new design by Ali and Steve. Our second collaborative design. Like the first couple of puzzles, it weighs almost 800g (1.1 lbs). Each piece is 70mm long and has a diameter of 19mm. This is a puzzler's puzzle. Perfect for fooling those who think they have seen it before. It looks like a standard interlocking Burr. It isn't. It makes a perfect quartet with Brass Monkey One, Two, Three, and Four . See our other listings to buy these puzzles as a group.
