Inspired by Da Vinci Code we plunged into the world of spies and cryptography and developed our own cryptex. The lock consists of two parts. Opens when you enter the correct combination of three digits. Inside the castle there is a small storage space for notes or small objects. Has an eyelet to attach to the bag. Create your own Da Vinci code for the lock from 1000 combinations (from 0 to 999). After assembling the model you will understand the operating principle of most modern code locks. The model, like all other Ugears models, is assembled without glue. Number of components: 34. Construction time: Approx. 2-3 hours.
