Order Custom Window Envelopes and get free shipping! Use these envelopes for mailing letters, invoices, or checks, that display a preprinted mailing address. Print your company logo, return address, and other artwork.
Choose from three popular sizes: #10, #9, and #8 5/8, each ideal for business use.
The #10 size is the most common for business purposes, perfect for mailing standard documents like business letters. With the #9 size being slightly smaller, mail important documents like business checks or anything that needs a closer fit. Choose the #8 5/8 for business checks printed from accounting software. Sealing options include traditional gum seal, and easy to use simple seal or peel and seal options.
Mailing sensitive items? Choose custom window envelopes with a security tint inside. The pre-printed pattern helps hide financial or health-related information. Need a little added security but not a tint? Choose a colored window envelope to match your brand or to help cover text written on a document inside.
