Our custom printed #10 window envelopes are white outside with a black tint interior, making them a smart choice for your business. These envelopes have a time-saving window that shows the recipient's address without the need for printing labels or hand-addressing. 

In addition to the 24-pound white paper stock and remoistening-seal rounded flap, these envelopes also feature our privacy black tint to keep your mail secure from prying eyes. We sell these quality envelopes in boxes of 1000 to help reduce your ordering frequency on supplies you use often. 

With custom printing, you can include several lines of text such as your business name, address or logo. You can even upload a design to our website when you order, or if you prefer, contact one of our friendly customer service representatives who can assist you. The Supplies Shops has free shipping on orders over $99, so you can save even more when you shop with us for your office supplies.
