#6 3/4 Envelopes - 3 5/8 x 6 1/2

Regular and window styles are both available here. #6 3/4 options span 20 lb to 32 lb paper for compact business and check-mailing needs. Representative colors include white, pastel blue, and pastel pink. Compact business-envelope options work well for checks, payments, forms, and smaller office mailings that need a professional paper presentation.

Selected address or form information stays visible for efficient mailing thanks to window options. Self-sealing options make compact #6 3/4 mailings faster to prepare in office settings. Paper and window choices help offices prepare smaller business documents efficiently while keeping address information organized.

#6 3/4 envelopes work especially well for small enclosures like checks and receipts, while also covering invoices, statements, payments, notices, reply mail, and forms. Small business envelopes support accounting teams, schools, nonprofits, healthcare offices, administrative departments, and businesses that send recurring mail. Recurring check and payment workflows are easier to manage when the same compact envelope construction is stocked consistently.
