I recently purchased this item, but I'm selling it because I'm using something else. This is a collaboration item between "studio CLIP" and "Miffy". I have opened the package and charged it once. *The double-sided tape is not included because I used it. I have not put it on my ears. Purchase price: 3990 yen <Notes> Double-sided tape was included to attach the main unit and the cover, but it didn't stick at all, and the cover comes off. Please use strong double-sided tape or take other measures. Instant purchase is OK. No price reduction is possible.
