I always like to throw a car cup holder tray into a bunch of different containers. I like to see how they will look and that they are compatible, so I can throw them all away once I’m done with them.
The question of how to use car cup holders as a tray is one that’s been debated since the first time we used them. The simplest way to use a car holder in your car is to put it on the seat belt. This is a great way to use your car’s roomy interior to store your favorite items, but it is also a hassle if you just want to put your bag in the backseat.
