The Puzzle is in near mint condition and has a great fit, not too tight or too loose. I used Eric's Renaissance Wax every now and then so the coordinate motion is really smooth (if you know how of course :) ). It has no damage and was stored under controlled humidity conditions, no smoking or animal contact.I am the original buyer from Eric. Buyer to pay shipping, please wait until auction end to determine shipping costs together.Original description from Eric:https://cubicdissection.com/pro...

Space is an aptly named caged burr puzzle designed by Dan Fast, this design is far out. The level 173 solution (145.1.5.4.4.2.2.2.2.2.2) is a tough challenge for even the seasoned burr solver to follow along with the solution file. Disassembly without aid is approaching the limits of human capabilities, but I am certain there are a select few out there with the ability and endurance to do so. The fourth photo is 108 moves into the solve.Wonderfully crafted by legendary maker Maurice Vigeroux, t...
