I found these Columbian #10 Laser/Inkjet envelopes after having all sorts of problems feeding and printing other brands through my laser printer. The normal office-supply house brand security envelopes seemed flimsy, and would misfeed or jam in my printer, the ink would smear, etc. Not so with these envelopes. They are of a heavier stock (24lb) and feed consistently well with both H-P laser printers and my Canon MP730 Multifunction inkjet printer. They might be on the pricey side of the scale if you are a higher volume mailer, but for small office/home office and personal use, they''re great.

These are good heavy weight envelopes 24# and they take laser print very well, for the price they are a good buy. I just wish they had been security tinted, but with their thickness it appears this may not be a problem.

Though these envelopes say they are security-tinted, they are not at least the two shipments I received aren''t.

My first order arrived well-packaged but incorrect. The description states CO131 #10 security envelopes, but I received CO138 NON-security envelopes. I did a return, which I must say Amazon makes very easy, but my replacement order was also the (incorrect) CO138 non-security type. Oh, well...I needed some 24lb envelopes, since my new laser printer doesn''t really handle my cheapie old 20lb envelopes very well. Even though these are not security envelopes, they are nice, and since the wait time is now 1-2 months, I''ll just order again some other time.

These are the best all purpose envelopes ever. Feed without fail through HP Photo Printer, HP Laser (ancient), and Lexmark AIO.

These are beautiful, bright white, well constructed envelopes with security feature that does not show through. Low tack seal acts to prevent high heat of printer from activating glue, sealing envelope, or jamming from printing process. I keep a glue stick on hand for the occasional corner or edge that may need a little extra seal. The freedom from printing labels and hand feeding envelopes is well worth it.
