We have 7 racers (5 of them drive) in the fam. I bought an array of lanyards & such 4 them. I cannot attest 2 the 'durability' of each (because they were Xmas gifts), but I can say that these small gifts were a HUGE hit for the teens. They use them on a daily basis, for school, fitness fobs, car keys, etc. I'm happy when my MXrs are happy, LOL.
