Purchased June 20, 2024 Color: White New main unit + 1 new button battery (already installed) I'm selling this because my smartphone is a folio type, and I found it inconvenient to remove it every time. I replaced the test button battery with a new one to check the operation, so you can use it right away. (The test battery has been removed.) I'm storing this at home, so I hope to sell it to someone who understands that.
