This is the gray color 3D printed version of the key chain puzzle "Chained Key" by Waier Creations. This is a jam packed puzzle with a lot of stuff going on and some really ingenius elements to the puzzling!
I hit a lot of walls during the solve and had to be really crafty to finally solve it.

Stored in smoke-free humidity controlled environment.
Can combine with other puzzles of mine which are listed.
Payment
via PayPal or Wise. PayPal has a lot of fees (FnF not possible), so
Wise is preferred, but not mandatory, and I can offer 5% discount if
using Wise.
