Fax rolls/drawing paper (Eaton Ford PE19)

I've found 5 unopened fax rolls from when my fax machine's print began to get poor.
They should be good for kids to draw on (long 'scrolls' which have been rolled up for a few years) but I don't know whether the drawings would last for ever, though they might as the paper won't have been heated.
I think I still have the fax machine as well if anyone would like it, with or without the rolls.
Happy to drop the rolls in to anyone in St Neots area when I'm out for my bike ride, though not the machine!
