## Customer Reviews

### ⭐⭐⭐⭐⭐ Satisfied
*by S***A on September 12, 2025*

Good gift for my little brother. Worth buying.

### ⭐⭐⭐⭐⭐ Great for Small Gifts or Money
*by L***N on April 2, 2025*

Not a hard puzzle per se but a good one. Makes giving money way more fun. This won't take days to solve but it is clever and I like it a lot. Great purchase. There is a small amount of room inside. You could fit small pieces of jewelry, gift cards, money or miniatures possibly.

### ⭐⭐⭐⭐ Fun and not too difficult
*by E***R on November 16, 2024*

It won't take you too long, but it's still fun.You can actually see how to open it if you look into the mechanism from the side, but most people won't find that before they solve the puzzle.
