These chic blue foil envelopes provide a creative and attractive way to post A4 size items. Their metallic blue colour helps them stand out from all other parcels, in addition to being highly protective and resistant to water and punctures. More fun than a standard padded mailing bag, they are just as reliable with a self-seal feature and a smooth bubble lining to cushion the contents. Our 324x230mm blue coloured envelopes conveniently fit Royal Mail's large letter size and are available in packs of 25.
