Are you like Turtle and have tons of caps? Have you tried packing your caps in luggage for a trip? Well you know it doesn't work well and you probably end up creasing the rim. Yeah I've had it happen, and it sucks. Well New Era has a solution and it's called Cap Carrier and it comes in 2,6, and 24 cap capacity.
I know I reference Entourage a lot, mostly Turtle, but hey I like the show.
