Frequently Asked Questions

AI
The standard size for business letters is #10, measuring 4 1/8 x 9 1/2 inches. This size fits three standard letter-sized pages folded into thirds, making it ideal for invoices, checks, and general correspondence.
Security-tinted envelopes have a grey or brown layer inside the paper to prevent content from showing through. This is essential for mailing checks, financial documents, or any information you want to keep private from prying eyes.
Peel-and-seal envelopes have an adhesive strip protected by a liner, allowing for quick, mess-free closure. Gummed envelopes require moistening the glue flap, which creates a more permanent, tamper-evident seal but takes longer to prepare.
