These lanyards are big enough to put your passport, foreign currency, coin, government issue ID, etc. So you can be hands-free to do whatever it is you need to do. Like going atv'ing, to a Waterpark, hiking, etc. This comes with two sizes included. One is a regular sized, clear, and waterproof vinyl that can fit credit/debit cards and id. Also, the second clear vinyl is big enough to fit your passport or foreign currency. The choice is yours.
