Custom Window Envelopes
Custom window envelopes make it easy to send business mail without extra steps. The clear window shows the address on your document, so there’s no need for labels or handwriting. Most customers choose a #10 size, which fits standard letters like invoices, statements, and notices.
You can print your logo and return address to create a polished, trustworthy look every time you send mail. This helps your business look more professional and makes your mail easy to recognize.
Popular options include self seal, which saves time and skips the hassle of licking envelopes, and security tint inside to keep private, medical, or financial information from being read.
Unsure what to choose? Start with a standard #10, self seal, and security option—it’s the most common setup and works for almost every business need.
