Box of about 1000 C6 envelopes (Pokesdown BH5)

I have a box of around 1000 x C6 size envelopes, with gummed flaps, the sort you lick.
114x162cm each envelope. (You fold an A4 sheet twice to fit it in). White.
They are several years old, but the gum still seems to stick.
They were left over when I retired from my business.
Please note: IMPORTANT - Fair Offer Policy applies - Please tell me why you’d like them.
(I could split the box, if necessary).
