While the move count is fairly low, it's easy to get confused on how to put the pieces together. Good thing the wood colors help indicate how everything is meant to come together! It's also a very early puzzle made by Brian Menolds, so the fit is fairly tight. Once the pieces are together, it's not easy to get the pie...

Tube It In, by Wil Strijbos, the early metal version. I acquired this from Wil in 2004. This was made from steel by Wil, the precursor to the wooden version made by Eric Fuller. It's small; about 2" in length. Unlike the wooden version, there is no magnet holding the puzzle together, so be careful when removing it from the box, or you'll have little square steel tubes all over the floor.US postage is $7.35 and international postage is $29.95.
