It started as a pet peeve. A poster stored in a tube unwound against the inside wall. It was turned upside down and shaken, but maintained its grip. A hand squeezed in the end and a corner was pinched and twisted. The corner creased. The corner tore. The poster was ruined.

When this story was related to architects, artists and engineers who use tubes of all sorts to carry their drawings or just store them, they finished our sentences. Then they chimed in with their own stories of drawings crumpled, artwork dog-eared, and upside down shaking.

There had to be a better way.
