Using this Kamen Rider Grease charm bracelet set is super easy. First, take out the 5 mini dog tags from the package. Then, simply attach them to the bracelet one by one. You can wear it on your wrist to show off your love for Kamen Rider Grease. When it comes to maintenance, keep it away from water as much as possible to prevent the tags from rusting. Also, store it in a dry place when you're not wearing it. Be careful not to pull the tags too hard to avoid breaking the attachment points on the bracelet.
