## Questions & Answers

**Q: Dose it come with its solution ?**
A: Actually, these puzzles do not come with the solutions. There is an email on the back of the product that you can write to for the solutions.

**Q: What size is it???????**
A: It is the size of a napkin holder. It will not fit on ANY human finger. This is good practice to learn how to assemble a real Indian puzzle ring but you cannot wear this ring conventionally. A child might use it as a bracelet.

**Q: Is this made in china ?**
A: Mine came with a bat in the box.

**Q: What is the inside diameter (id) of this puzzle ring. i've read it's too big to be worn as a ring, but please measure side to side (inside). thanks!**
A: The inside diameter is about 1.6 inches (between the 1.5" and 1.75" markings on my tape). It is too big and too heavy to be worn as a ring.
