It doesn't look much but I received the above pieces in a very neat package from the amazing Jack Krijnen. These are a set of 6 quaternary burr pieces to go with my power tower set. This set means I can now mix and match the pieces to produce some very entertaining sequences. I love it! I'm also waiting for a new version to come out with an entirely new design.
