Columbian #10 Business Envelopes, 4-1/8 x 9-1/2 Inches, Self-Seal Closure, Side Seam Envelopes, White Wove, 500 per Box (COLO147)

Product arrived before original estimate and was a competitive price. We just received it, so we haven't tried the adhesion yet, but I did notice the paper looks a little thin, hence the lower sheerness rating. We'd probably buy again, though, for what we use these, provided the adhesion is good. My main complaint/negative review, however, is not for the product, but wasn't able to put this in the delivery feedback. I hate that Amazon often doesn't abide by my detailed delivery instructions. What is the point of giving office hours when they like to attempt delivery AFTER office hours?! In this case, it wasn't critical that I receive it on time, but to attempt delivery 2 days in a row after hours doesn't make sense. Fortunately, the back-up plan of delivering to our daycare adjoining us worked last night, but PLEASE TELL AMAZON TO DELIVER DURING OFFICE HOURS!

We have bought these previously but this last order a large percentage of the envelopes have opened because adhesion was not maintained. Ended up having to put a short strip of tape for security. Will be looking for another brand on the next purchase.

The media could not be loaded.  I am placing these inside of something else. I have not gotten through the entire box yet, but a large portion of them are not fixed down on all sides so what place in the envelope may not stay.

What can I say about an envelope other than to say ITS A GOOD ENVELOPE!

We switched to the pull tab envelopes several years ago and usually get them from a local retailer but I saw these on amazon for less so I bought them. They are good, usable envelopes, but a little thinner than the others we had been using. I will probably go back to the others after this box is used up but they are still a good buy.

Once again I am amazed at how much the big box stores jack up there prices only to tell you that you are receiving a discount. I contacted a few office supply stores for these envelopes only to find outrageous prices. Do yourself a favor and buy these amd save money on a good product.

I like that these envelopes are self-sealing. The paper is soft and flimsy though, as if it was made from standard-grade paper instead of the slightly stiffer envelope material. My boyfriend said they were like paper pretending to be envelopes. Still worth it to not lick 500 envelopes!

Excellent envelopes, very good product. Glad I bought these. I really liked the fact that these Envelopes are the ones that you don't have to lick them to close them. Simply take the piece of paper off the sticky part of the envelope and fold it over and the envelope is sealed. The shipping was fast and I have had no problems with this item. I would recommend this product to everyone.
