Columbian 9 x 12 Clasp Envelopes, Gummed, 24 lb Kraft Multipurpose Envelopes for Mailing, Storing or Filing Documents, 25 per Pack (COLO340)...

These are good envelopes, the paper is high quality, the metal clasp feels sturdy, and the gummed seal also works exactly as expected. I have used these to mail out documents and everything arrived as hoped, zero issues with quality or durability of the envelopes. My only "issue" is that these cost as much as "name brand" Mead envelopes, which might be an issue for some. I would say that the quality is there so it's not like these are as expensive but for an inferior product but it's just something to keep in mind. Overall, these are great envelopes, ones that I have used and will happily recommend to others!

I primarily use these envelopes for filing and organizing paperwork at home. They are a little on the thin side compared to the envelopes that I am used to using, but they do the job. I'd be hesitant to use these for mailing - I'm not sure that they would hold up. It's probably worth buying a heavier weight or actual padded mailers. Overall, they are pretty standard for what they are. The price is about average for what I expect for the quality of these envelopes.

Manila envelopes are one of those items that you don't need often (for the regular person that is), but when you need one, you really need one. We try to have a stash on hand at all times, for our more sensitive documents. These are great quality - sturdy, not flimsy, and stays shut once the adhesive is activated. They're priced a tiny bit high, but it seems like everything is nowadays!

These envelopes are great especially this time of year as taxes are being prepared, sent, and stored. These envelopes are slightly thicker than an office store brand I previously had. The adhesive bonds well and the clasps are on par with others I have used. At $12 these come out to just under 50 cents per envelope which is roughly twice the amount of the average pack of 25. These did seem slightly thicker and the adhesive does make a good bond. I feel like they are a good quality envelope at a higher price making them not a terribly great value.

These envelopes are made well with good seems and clasps. They are made from a little lighter weight paper than the ones I typically use. So if you are using them for mailing and not going to stuff them full they are probably fine. I use them primarily organizing documents at the end of the year before I file them away and they will be fine for that.
