Brass Monkey Three. Just two rings engraved on the end of each piece differentiates it from Brass Monkey One (no rings) and Brass Monkey Two (one ring) 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 triplet with Brass Monkey One and Brass Monkey Two. See our other listings to buy these puzzles as a group .
