The Tile Sticker 2020 is meant to be disposed of when the battery dies… but the internet told me otherwise. Unfortunately, opening the sticker up deforms the rubber seal which makes it hard to snap the pieces back together or protect the thing. Fortunately, I found Monikr's remix which I've scaled down to friction fit the sticker's plastic housing and also created a hole in the back to see your QR code and to poke the sticker out.
