Anker Eufy Smart Track Link (for Android) (Anti-Loss Tag) I just bought this in September, but I'm selling it because I'm switching back to an iPhone. One with the insulating sheet is unused, and the other two are used but in good condition. Since some items are used, please refrain from purchasing if you are sensitive to used goods. I will ship via Nekopos. To prevent swapping, I will not accept cancellations after shipping.
