Your cart is empty.Columbian #10 Security Envelopes are the perfect all-purpose envelope for letter-sized business documents. Each #10 envelope is 4-1/8 x 9-1/2 inches; designed to fit a letter size sheet (8-1/2 x 11 inches) folded into thirds. Security tinted envelopes have a scrambled blue pattern printed on the interior that conceals the contents. The Release & Seal strip peels right off so you can press to seal without any moisture. These self seal envelopes are inkjet printer compatible, though not recommended for a laser printer (use address labels instead). 24 lb white wove paper with side seams give these business envelopes a professional appearance. Overall envelope dimensions are 4-1/8 x 9-1/2 inches. White. Box of 500.

I write 100 letters a week for my job and this maximizes my value per letter great quality, great stickiness.

Great value for the cost. These envelopes seal well. They are thick and you can’t see through them.
