If the resin part is worn, please replace it before you lose your key! This is a cover for MIWA keys. The hole for the metal key is square, and it is for JC. Please note that it is not for PR. Most of the covers sold online are for PR, and JC keys will not fit properly! If you shave off part of the PR type, you can force the JC key in, but it's difficult for amateurs to do it well → as the resin becomes thinner, the corners will crack when worn. I am one of those who mistakenly purchased and modified it. It is indeed safer to use a JC-specific cover for JC. Please check the engraving inside your key. The price is for one set. I had quite a bit of trouble obtaining these, so I am selling one set that I purchased as a spare to share with those who are looking for it. The following is automatically generated by AI.
