Just used my first one today. Perfect for sending tote bags.
August 15, 2019
Very happy with this product. The size is perfect for what we need them for.

Perfect and exactly what we needed for our project in shipping over 480 multi pack DVDs. Closed easily and solidly with built in tape.
May 27, 2018
The length of the envelopes is a bit less than advertised. My 8" x 12" photos just make it into the envelope.

The company is excellent because of the quick delivery. The outer package was damaged, but it did not effect the box with the envelopes.

I recommend "On Time Supplies" over "Amazon" what I normally chose.

The SMD89540 - Poly String & Button Envelope does not have a view cover page insert option. We do offer PFX90016 - Poly Booklet Envelope, Side Opening, which does offer a cover insert option.

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.
