Technics AZ80-K Replacement Mesh Sheets 【PNYSAAZ80】! Purchased from the official Panasonic store♪ There are types A and B for the mesh sheets, and this is type A. We recommend confirming which type is compatible with your earphones before purchasing☆ Just a personal experience, but My hearing in one ear became poor, and I thought I'd try replacing the mesh sheets before sending them in for repair! It was resolved surprisingly easily♪ (I felt a bit bad, wondering if they were that dirty...) I will cut two sets of sheets from the sheet and send them in a separate zip-lock bag. I've set the shipping method to "regular mail" to keep the price as low as possible, but this method does not offer tracking. For an additional 100 yen, you can change to "Yu-Packet Mini" which offers tracking. Please let me know in the comments if you'd like to change the shipping method☆ I will then adjust the settings. No claims or returns accepted. I am also selling [one set] separately. Please take a look if you're interested♪
