The Slim Tiles are fantastic for wallets and Passports.
The super duper small one is the only one that will fit inside my Umbrella (Blunt Umbrella: Model - Metro) - Cost 100$ AUD or so.
This was a must have and great purchase for myself as I'm forgetful af - I'll probably have to get the premium version in the future in case I leave home without my stuff XD
The Tile Slim is WORTH it. If it's too much, just sell the unused ones or give the unused ones away :)
The world’s best-selling Bluetooth tracker, the NEW Tile Mate attaches to keys, purses or anything else you couldn’t live without. Use Tile adhesives (sold separately) to stick it to any flat surface like a laptop so you can always find your things.
