riraku-life (Relax Life) This is a static electricity removal bracelet made of silicone. It can also be used on the ankle. It can be used even when wet. I bought it about 3 years ago, so I think it's probably an older model. It's a little more difficult to put on and take off than the new models, but it's still usable. The regular price was about 1500 yen per piece. Thank you for looking.
