This is a fun and challenging pocket-size puzzle with a much larger challenge. In fact, three challenges as I include two expansion packs. The pieces not only have different length under posts, but some also have embedded magnets. Ahhh, magnets :-). Of course, the tray also has different depth holes, some with their own magnets. It's challenging just to fit the pieces together properly, let alone get them to all sit fully inserted and level across the top! Great puzzle in excellent condition.

Please wait for me to contact you after you win so that I can get your address to calculate shipping and a final total. PayPal Friends & Family is very appreciated! If you are hoping/planning on getting more than one of my items then let me know and I'll wait until you are done.
I accept international bidders/winners, but please be aware that due to recent USPS issues I will ONLY use UPS for shipments outside the US. This may mean additional fees for you, the package receiver, but it's better than packages being rejected by Customs and never making it to you.
