Description:
Getting items ready to mail can take valuable time away from other critical work functions. How can you simplify the process? Choosing the right envelopes is a smart solution to this dilemma. The Supplies Shops has custom printed #10 self-seal window envelopes with an interior blue tint that are quick and easy to use.
Instead of sticking with the same old standard envelopes, you can order these custom self-seal envelopes and use our printing services to add your company name, logo and address. The envelope window allows the recipient’s address to show through, and with the easy-to-use flip-and-seal closure, your mail can be processed and ready to post in a fraction of the time.
Not only that, but our custom self-seal envelopes include an interior blue tint to help prevent tampering. The more 500-count boxes of envelopes you order, the more you save, so take advantage of our volume discount and free shipping when you spend more than $99.
