Unlike traditional envelopes, these are specially treated to withstand the printers' heat. So even after the labels and have been added, the gum adhesive will remain just as tacky as it was prior to being exposed to heat. Other than that, these open side diagonal seam envelopes function like a typical #10, making them an asset in the office mail room. Envelope/mailer type: business/trade; envelope size: 9 1/2 x 4 1/8; closure: gummed; trade size: #10.
