This is a wonderful and tricky packer designed by Koichi Miura and produced by MINE.
This design won Jury's honorable mention in 2021 International Design Competition.
Goal is quite simple - pack the 4 pieces inside the box. No force or tight moves required.
Some copies of this puzzle had loose tolerances which allowed for unintended solution. From what I've tested, that's not possible in my copy and only the intended solution works.
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.
