Buying Guide

Choose the right size and window layout

Match envelope dimensions and single or double window placement to your invoices or shipping labels to avoid reprinting or folding documents

Pick closure and sealing style

Decide between self-seal for speed, traditional gum for archival security, or clasp closures for reusable document storage

Consider paper weight and finish

Heavier stock (e.g., 24 lb) and linen or cotton finishes convey professionalism and resist show-through on single-sheet mailings

Factor quantity and unit cost

Compare box and pack counts—larger packs like 250–500 units lower per-envelope cost for high-volume mailers

Match aesthetic needs to branding

Choose ivory, kraft, or specialty lined options to align envelope appearance with company stationery and presentation
