Buying Guide

Choose the right size

Match envelope size (A7 for 5x7 cards, A4/4 1/4 x 6 1/4 for smaller cards) to your card dimensions to avoid bending or extra postage

Prefer peel-and-press seals

Peel-and-press or self-seal closures save time and reduce mess compared with lick-and-stick, important for bulk mailing

Check paper weight

Heavier paper stock (around 80 lb/text) gives a premium feel and resists bending during transit

Pick color that complements cards

Colored envelopes like seafoam, mandarin, or lilac enhance presentation but confirm contrast for addresses and postage legibility

Buy pack size for volume

Select 250–500 count packs if you mail frequently to get consistent color and avoid frequent reordering
