Every office still needs envelopes, and we have a selection of popular and commonly used sizes and styles. From gummed, self-seal and peel-and-seal white envelopes with and without windows in a range of standard sizes, to gussetted envelopes for those bulkier items, and board envelopes for photos, certificates and other documents that mustn’t get bent.
