Anyone need some cardboard tubes?

[karohemd]

I have six of the buggers (dlab7.com deliver their large prints in tubes rather than flat-packed, 8 or 9 per tube and when you order a few, you get loads of tubes - but still only pay 50p for p&p).

They are quite sturdy, have removable plastic caps on both ends, diameter is 8cm, length 35cm.
I guess these would be of interest to the regular ebayers among you.
