Running out of envelopes can slow down your mailing process – and your business. Our custom printed #10 window envelopes come in boxes of 500, and we offer volume savings when you order multiple boxes. 

With their 4-1/8-by-9-1/2-inch size, these custom #10 envelopes come in handy for mailing statements, invoices, correspondence and other important documents. Our custom #10 envelopes feature 24-pound white paper stock made of 30% post-consumer waste, a lower-left window and a standard flap. A black recycled logo pre-printed on the back indicates that this envelope is a more environmentally friendly choice.

The Supplies Shops offers customization to give your envelopes a professional look and make your mail more efficient. We can print your company name, address and logo to identify your mail to its recipients. Choose your preferred font style and ink colors, or talk to one of our friendly customer service representatives who can assist you with your custom envelope order.
