Overview
Builders working at a tabletop assemble a wooden sphere-shaped treasure box with a tray for storing small items. A mechanism for setting a combination code locks the box once it is finished.
A working lock mechanism makes the finished model do something rather than just sit on a shelf. The limit is that the listing names no tools, glue or instructions and does not say how long assembly takes.
Who it's for
Hobbyists who like patient, hands-on builds and want a small box to keep things in afterward. Younger kids are below the listed age, and anyone who needs assembly time or tool details should look elsewhere.
Pros and cons
- Working combination lock
- Storage tray or compartment
- Skill and patience project
- Assembly steps not described
- Build time unknown
- Tools and glue not named
Performance notes
The finished box depends on how accurately the wooden parts are placed, since the lock mechanism needs them aligned to turn. Patience and fine hand skill matter more than speed with a mechanical build like this.
