Wanted - Black A4 ring binders - about 10 or 15

Hi folks - I was wondering if anyone has about 10 or 15 black A4 ring binders (not lever arch, just normal rings) that they no longer need.  They needn't be in perfect condition, but the rings do need to work properly.  I can collect tomorrow or Saturday more or less anytime, or Sunday late afternoon/evening.

(I've also asked on freecycle, so if you see that post, it is also me.)

Thanks!
