* Product composition
PK ring (silver, uneven) 1mm inner diameter 18mm ring, 1 transparent case

* Size
18mm inner diameter (I have measured the inside size of the ring, not the outside of the ring.) Therefore, please choose the size of the inside diameter of the ring that you usually put on and think about the deviation.

* Product directing
The magnet ring can be used for various production. Especially, it is a necessary tool for directing coins made of magnets.

* Points to consider when purchasing products
Do not drop or give strong impact. It can be broken because it is a magnet ring. Please keep away from electronic products such as mobile phones because there is a magnetic force. You are responsible for this.

* If you have sensitive skin or metal allergies, please think carefully and purchase.
