-Unique mechanical lock
This is a toy puzzle. You may even consider that this is a tactical toy. All designs are locked. Rotate the drum (ring) and the container is OPEN, of course, if you know the code. Your money, flash drive or other secret personal belongings are securely hidden in this small portable vault. Key combination is unique for protection!
All parts was 100% handmade.
I have build over 20 Cryptex using this mechanical lock technology.

Photos 4-5-6-7 and result 9-10-11 (a chemical reaction 1hour)
