Can storing blueprints and other rolled documents be difficult?
We manufacture a triangular plastic storage tube that can store rolled documents, posters, blueprints, etc. while keeping 3 corners of the inside vacant and allowing easy access to the rolled contents inside, unlike a circular storage tube. The triangular storage tube can not be dented or crushed, keep the documents safe from any damages.
The tubes can also be stacked and easily shipped.
Is this something that is needed in the Engineering Marketplace?
