A simple band that clips to the side of Ikea Vesken shelves and trolleys. Meant to be printed in the filament color to show what it looks like, unobstructed by the container it may be in, as well as a placeholder to know where to return the filament to when you're finished printing with it.
I use both Lock & Lock and PrintDry containers to store my filament, and Vesken Shelves to keep them organized. I've also created a Filament Container Stand to make sure they stay upright.
