It is on the post in the center of the heart. Overall the rest has minor scratches from puzzling. Buyer will pay shipping and will be calculated at the end of the auction.

Brian's description: Initially I was going to refer to this as a TIC with training wheels, due to the fact that it is one of Andrews recent designs featuring only 3 pieces. Then I thought better of it when I spent two nights trying to put my prototype together. I still must believe that this is a bit easier than many of his other designs but it is still fun! And it still has 5 rotations in spite of there only being 14 moves. If you've never tried a TIC before, this is a great place to start. I...

Original description (2008) from Livewire Puzzles :Contrary to present-day thinking, our Open & Shut Case puzzle requires the solver to think "inside" the box. To open the miniature metal briefcase requires the puzzler to perform a series of steps in a specific sequence. When done correctly the case will smoothly swing open. Frustrated puzzle solvers should note it is unnecessary to remove the briefcase's hinge pins. A sharp ear, a light touch, a keen mind and patience are the keys to this puzzl...

I accept Paypal and Transferwise.

Yavuz invented this great new style of puzzle combining packing and sliding. The goal is to place the 4 pieces into the box, face up. Trickier than it looks! Number 8 was one of the harder puzzles of the set - to me it was the perfect difficulty. Hard enough to give a sense of achievement when the final piece fits, but not so hard that you are tempted to break anything! Will combine shipping. Shipping costs and handling fees (4.5%) will be calculated at the end of the auction. I accept...
