This is an amazing packing puzzle designed by Hajime Katsumoto and crafted by MINE (Mineyuki Uyematsu).
The goal is to pack all pieces inside the box which has a quarter circular entry hole. The lid moves, so the quarter opening rotates around. The solution is very elegant and satisfying.
Stored in smoke-free humidity controlled environment.
Can combine with other puzzles of mine which are listed.
Payment
via PayPal or Wise. PayPal takes away roughly 9% (fee + currency
conversion, FnF not possible), so Wise is preferred, but not mandatory.
