## Description

Lock Puzzle is a key puzzle decompression toy, suitable for dismantling metal toys for the elderly and children. It is not a lock that can be used. Please pay attention when buying.

Review: Give it a Shot - Bought for a DnD game so a player would have to solve the puzzle in the real life and it was a hit. A great, simple, and satisfying puzzle.
Review: LOVE it! - I can't believe the negative reviews. The weight, the quality of the casting, it's just beautiful. Feels old and, I dunno, nice. Yes, the puzzle is a little easy, but that makes it a great gift for non-puzzle-people. There are only two Hanayama I currently find suitable for that purpose. I just can't imagine regretting spending a few dollars on this thing. If you don't like it, give it to a stranger in the grocery store and get your money's worth that way. I'm buying more for that purpose.

## Questions & Answers

**Q: Is there more then just opening the lock part? Or is it just the 1 step to solve the "puzzle"?**
A: Hello! This is a primary puzzle, which is to discover and explore how to open the lock. Many people will use the key to open it. The lock is closed. The fact is that the lock itself can be opened.

**Q: How difficult is this?**
A: it took my wife 7 minutes and my 9 year old a half hour. its a great puzzle. definitely on the easier end of the spectrum, but still difficult enough to be satisfying once solved.

**Q: What level is recommended for a 12-year old young man?**
A: that depends heavily on the young man, my 9 year old enjoys puzzles and will tinker for around 30 min before taking a break. i like to start around level 1 or 2 on a 10 point scale regardless of age until familiar with basic puzzling techniques. the shuyue lock was a great start for my boy and wife. i think that is a 2 or 3.

**Q: What is the size of each puzzle?**
A: fits in 1 hand
