Are the objects waterproof and durable?

Yes. All three objects are waterproof and built to take daily wear. They are made to be forgotten, in a good way.

• Water and rain: waterproof, fine when you wash your hands, get caught in a shower, or wear it swimming.
• Daily friction: pockets, bags, keyrings, and being handled dozens of times a day.
• Temperature: normal indoor and outdoor use.

The badge is thin and flat, so your phone still lies flat on a table, and its professional 3M adhesive holds it firmly on the back of your phone or its case. The card is the size of a bank card and slides into a wallet slot. The keychain takes the life of a keyring without complaint.

There is nothing inside that can wear out: no battery, no moving part, no screen. See does it need a battery.
