I bought them to use when mailing posters I'd bought, but still have hundreds left.  They are in perfect condition.  Although light, they are bulky, so delivery/collection arrangements will need to be carefully considered.  I've put 'collection only', but am happy to work with you on delivery if you'd prefer. 

I've put £50 for 100 but, if you take the lot, am willing to offer a discount.  Any questions, please ask.
