Would pay an extra dollar for these without inch thick plastic packaging that requires a chainsaw to liberate.

Thanks op.

Also there's a discount on the 2-pack as well: https://slickdeals.net/f/19937298.

I was able to get the discount on both.

Fyi these fit a 2019 cx-5 and 2018 mazda 3 key fob

This is the wrong size for an airtag, you need 2032

phoinix used to almost always leave key info out of their posts. Sizes of TV's, battery sizes, always some key info that you'd need to know if the deal was something you wanted for the price. Then they got way better. This is the first one I've seen them slip on for a while. At least the picture shows it.

I heard these begin to lose charge/corrode when they're exposed to air. Maybe that's why you can't open these without needing a damn bandaid.

Agree, the real battery is what the plastic packaging does to your hands.

Good idea but these use a dye and when you get them wet you look like you robbed a bank.
