Several of the envelopes came sealed provably due to long time storage
The Kraft Clasp Envelope is of high quality, offering strength exceeding that of many competitors. Price and service by On Time Supplies make it an excellent value.
The Jiffylite Self Seal Mailer is of high quality with strength that serves my purposes. The bubbles protect contents of the paperback books that I ship very well. I consider this to be a product of excellent value.

Can you use these envelopes in a laser printer?
asked by Julie MacCarthy on August 27, 2015

In general, Southworth® 100% Cotton #10 Resume Envelopes are fine to use in laser printers. You may need to adjust one or more of your printer setting for the best results. I encourage you to contact the manufacturer of your printer for further assistance.
