Buying Guide

Choose the correct size

Match envelope dimensions (common: 2 1/4 x 3 1/2 and #7 3.5 x 6.5) to the coins or items you ship to avoid shifting and damage

Consider paper weight and durability

Heavier stocks such as 80lb provide better protection and tear resistance than lightweight paper for frequent handling and mailing

Pick the right closure type

Self-seal closures speed packing and reduce the need for tape, while traditional gummed flaps may be preferred for archival or reusable needs

Color and organization

Colored options like sunflower yellow, lilac, or wasabi green help with sorting and visual inventory control compared with plain white or brown kraft

Bulk pack vs smaller quantities

Bulk packs (for example 250–500 count) lower per-unit cost and suit high-volume operations, while smaller boxes are easier to store for occasional use
