    Envelope - Heavy Paper, Short Sticky
  

*by K***7 on Reviewed in the United States on March 1, 2014*

Good envelopes.  It prevents you from having to run to Staples/Office Depot/Office Max/Walmart to go and buy some envelopes.  Believe it or not, I spent about 30 minutes reading reviews on which one was better than the other.  After 30 minutes, I gave in to these guys.  It's a clean box, heavy duty paper and had the least negative reviews about the adhesive.  They have worked great for my weekly expense reports, bill payments and occasional letters sent.  I do double-check to see that the adhesive will stay each time and have been surprised to see that they work quite well.  If 1/4" extra adhesive was added to each end of this, 5-stars all the way.  There is just something about the ability to lift the corner of an envelope open that I do not like.

    Not certain what I received...
  

*by J***. on Reviewed in the United States on October 30, 2018*

I had anticipated envelopes identical to the Columbian No. 10 GRIP-SEAL SECURITY 24lb inside security ink 75503 that typically comes 500/box in a heavy green box. I expected a cheaper box, which this is. I did not expect lesser envelopes, which these seem to be.1. The grip seal. The Columbian envelopes I expected say "Columbian Grip Seal" across the removable strip. These do not. Not a big deal, except the Columbian strip is secured flat against the envelope, so it moves nicely through my printer. These envelopes have a cheap strip with wrinkles that I doubt will provide a consistent printer quality. In fairness, I have run a couple envelopes through and haven't had a problem.2. The security ink. The Columbian Grip Seal I expected have a bluish-purple random ink printing pattern on the inside of the envelope and flap. These envelopes have a lighter blue random ink pattern with fewer and larger little marks on inside of the envelope only, not the flap - less secure (but probably adequate).3. The cut. The Columbian Grip Seal I expected have about a 100 degree corner on the edge of the flap. These have a rounded flap. I don't care about the flap edge geometry, but it is different from what I expected.4. No branding on envelope. Columbian Grip Seal envelopes have always had the mark "Columbian Grip Seal" on the removable strip. There is no branding anywhere but a sticker on the outside of the box.The deviations from my expectations lead me to question whether I did indeed receive Columbian Grip Seal envelopes at all. These are ok envelopes, but I sought out Columbian Grip Seal because they are the best I could find. These are not that. Had I known these would be what I received, I would not have ordered them. But, I think they will probably work so I don't intend to return.

    Great all around business envelopes
  

*by J***N on Reviewed in the United States on December 20, 2013*

I operate a small e-commerce site producing QR code labels. These are a perfect all around envelope to ship my labels out in. The size will accommodate a lot of labels or additional documents. The security lining prevents unwanted viewing of contents. Best of all the self sticking label. I would not be a happy camper if I had to lick envelopes or use sponges all day to ship out my products.
