Sturdy cardboard tube 2m long (Greenstead Green CO9)

Sturdy cardboard tube 2m long, internal diameter 11cm. It could probably be cut into shorter lengths with a small saw. Came with our new coir matting. Seems a shame to destroy it as I'm sure it could be used for something but I can't think of anything we could use it for, so anyone who would like it is very welcome to have it.
