アイコーチ交換用ボール

Q: I need to get a new ball for eye coach, but I also need the attachment bolts for the ball. How much are the bolts

Hi! Please place the order for the ball and then send us a message requesting that we send you the bolt as well, no charge!

Q: I need a new ball but I also need new rubber guards where the bolts are at. How do I replace those?

If you can find the rubber pieces, it’s easy to replace. Just unscrew the ball and bolt, then you can just slide off the old rubber piece and put on the new one. You can also buy a new replacement arm.
