A brand new box of 500 C5 (229 x 162 mm) envelopes, self seal, white, paper quality 100 gsm currently selling at £31.19 including VAT (£25.99 before VAT) from main stationery catalogues. I am selling for £10. Best to be collected from N8 or can meet half way. Can be posted, but I have already checked, it costs £12.98 second class parcel because it's over 2 kilos. Need to sell as I have lost my office and have many things as surplus.
