Buying Guide

Choose the right size

6x9 is common for folded flyers and booklets; confirm dimensions match your inserts to avoid trimming or folding

Pick a closure style

Self-seal closures save time for high-volume mailings, while standard gummed flaps are fine for occasional use

Consider paper weight and finish

Heavier stock (e.g., 80 lb text) and coated finishes provide a premium feel and better protection for printed materials

Check color and presentation

White and natural stocks are versatile for mailing, while black or holiday colors suit branded or seasonal mailings

Buy appropriate pack sizes

Bulk packs (commonly 250) lower per-envelope handling time and keep supplies consistent for recurring mailings
