This metal interlocked burr has four unusual shaped pieces that interlock to make a shape like a cross-hatch or a hashtag or the number symbol #.
The puzzle definitely lends itself to metal, heavy metal, rather than wood because of the odd shapes and angles would be difficult to make strong enough to interlock the way they do. With this type of puzzle, it’s taken for granted (unless otherwise stated) that no force is required to do the puzzle and that’s still true here but with this one, it would be difficult to break anyway!
This bright blue anodised pieces are very attractive and the shape lends itself to a modern theme. Great for the desk of that person who’s hooked on Twitter and other social media! It can move quite a lot without coming apart. It won’t just fall apart by mistake that’s for sure.
