I'm selling this because I bought it but don't use it much. Operation has been confirmed. I will charge it before shipping. Reference price: 14,300 yen The following is quoted from the official website: An eye mask that can care for the eyes with 4 modes. ● Two low-frequency terminals stimulate the acupoints around the eyes, comfortably stimulating the area between the eyebrows. ● 16 soft heads gently stimulate the area around the eyes! It does not directly compress the eyeballs and does not put a strain on the eyes. ● Convenient because you can see! Designed so you can see a little in front of you while wearing it & healing melody.
