Universal® #10 security tint envelopes with peel and seal strip are the perfect business envelopes for mass mailings or everyday correspondence. The self-adhesive closure makes large mailings faster and easier by eliminating the need to add moisture to the envelope flaps. Simply peel back the strip on the back of the envelope flap, fold and press the flap to close. The adhesive strip creates a full, secure seal across the envelope’s width to prevent opening. The envelope is also resistant to tearing and splitting; great for mailing thicker documents. The paper’s printed security tint pattern helps protect privacy and confidentiality by making its contents very difficult to read through the envelope.

Suitable for the secure mailing of checks, invoices, legal documents and other sensitive information. The windowless design of these envelopes also further safeguards the security of your correspondence by not allowing for any means to look inside. The solid front panel provides ample space for printing with most inkjet and laser printers, or may be labeled or hand-addressed. From mass mailings to single letters, these #10 window envelopes with peel and seal strips are able to be quickly and easily addressed, for faster sending. Manufacturer’s limited warranty valid for one year from date of purchase.
