Buying Guide

Match envelope size to card

Choose A7 for 5×7 cards and A4/4 1/4×6 1/4 for smaller notes to avoid bending or excess empty space

Check paper weight

Opt for 80 lb text or similar stock for a substantial feel that protects cards in transit while remaining mail-friendly

Prefer peel-and-press or self-seal

Peel-and-press and self-seal closures speed prep and provide a cleaner, more secure seal than traditional lick-and-stick

Consider color and finish

Neutral tones hide wear in transit while colored options (seafoam, lilac, mandarin) add a personal touch that complements your cards

Buy counts that match use

Choose 250–500 packs if you send regularly to get better per-envelope value and avoid frequent reorders
