#10 Window Envelopes

#10 Window Envelopes (4 1/8" x 9 1/2") offer a professional and efficient solution for business mailings. Designed with a clear address window, these envelopes allow recipient information printed on your document to show through—eliminating the need for separate labels and saving time on large mail runs. Ideal for invoices, statements, checks, payroll, and everyday correspondence, #10 window envelopes pair perfectly with standard 8.5" x 11" sheets folded to fit. Custom printed envelopes showcase your company logo and return address for a polished, branded look.
