Stick this in your car cupholder so you can fit your large waterbottles (ex: Nalgene)
Unscrew top and bottom to reveal “secret” compartment
Great for just holding stuff in the car in general
Print Notes
You can print the tall or short top version, but I recommend the taller one b/c it will make you worry less about stuff falling out (it's not as tall as it appears at first)
