Coin envelopes are a great choice for handling transfers of office keys and similar small items. They can hold your promos and business cards with ease, and durable construction helps them last for some time in storage.
Secure Seals Most envelopes feature either a gummed or self-adhesive seal. Self-adhesive seals are a great choice for when you need to send many envelopes or don't want to risk contamination.
Durable Standard coin envelopes feature durable constructions that help protect the contents from both prying eyes and the elements. For even greater protection, try poly envelopes.
Versatile Coin envelopes aren't just for holding coins. Antimicrobial versions are excellent for businesses that regularly transfer small pills or capsules between labs or departments.
