Whoa! Very nice update, Claus! I am not an expert in rare twisty puzzles, I just see that there are some very rare ones and complete sets of novelties here. However, the non-twisty updates are impressing:
A Cutler Cube (Eric Fuller version -- now you have a reasonably sized version, too!
), two different variants of the "Hexadecimal" puzzle (including one rare original with packaging), Changing Partners, Wil Strijbos' First Box and the new EGG puzzle. an original Oskar Cast puzzle, a King puzzle by Marcel .... and then (believe it!) a Popplock T1! Not to forget a bunch of Kamei's nice boxes ...
Impressive! Looking forward to see all these puzzles in person.
