Mead 9X12 Clasp Envelopes, Office Pack 20 Count (76020) Review:


This thing is excellently manufactured. For mailing 4 x 6 photos and letters to the grandchildren, the size is ideal. The clasp, which I cover with some Scotch tape, is adequate, the material is strong, and the adhesive adheres effectively. I advise it!

Clasp Envelopes – 10x13 Inch Brown Kraft Catalog Envelopes with Clasp Closure & Gummed Seal – 28lb Heavyweight Paper Envelopes for Home, Office, Business, Legal or School 30 Pack 10x13, Brown Kraft Review:


I've encountered across flat clasp kraft mailing envelopes that were so fragile that I didn't feel it was safe to actually ship out documents in them. The quality of products like these can vary significantly by brand and vendor. A decent rule of thumb is that, in most cases, you get what you pay for, so if the price looks incredibly low, the quality will most likely follow.These are of above-average quality and provide enough durability for mailing documents. As long as you aren't compressing the contents too tightly, the paper quality is adequate; but, in that situation, I would advise using heavier-weight envelopes. The bottom flap's glue seal appears to be reliable. Although the flap edges on the envelopes I used didn't glue completely flat, the adhesive you moisten to close the envelope is powerful. Although I suspect the envelope would open while in transport, you will probably need to add a piece of packing tape down the bottom of the flap if you want a seal that is fully secure.These are eventually OK for delivering a small quantity of documents, but I would seek for something thicker if I were mailing collectibles like autographed photos or something like, where cardboard will be included to prevent the contents of the envelope from bending.

Clasp Envelopes – 6x9 Inch Brown Kraft Catalog Envelopes with Clasp Closure & Gummed Seal – 28lb Heavyweight Paper Envelopes for Home, Office, Mailing, Business, Legal or School 6 x 9 Manila 30 Count Review:


Well, as luck would have it, USPS declared the boatload of similarly sized envelopes I have to be "large envelopes," which resulted in higher prices. So I discovered these. They fall within the "letter" tariff structure, so I don't have to pay for postage. These can be sent with a regular first class postal stamp, which costs 48 cents (on a meter) and 49 cents for a stamp (I believe that's correct). Anyhow, these cost less to mail than what I had previously.I researched it. The maximum "letter" size is 6-1/8" height by 11-1/2" long. My other envelopes were 6-1/4 in size "I was charged the "big envelope" fee as a result. Yes, it's somewhat excessive for 1/8 ". I guess.

Columbian Clasp Envelopes, 6 x 9 Inches, Brown Kraft, 100 Per Box (CO955) Review:


I bought these since they had the best customer reviews on Amazon for 6x9 envelopes in their price range.They're excellent envelopes. Although a little on the thick side, the paper weight is sufficient for what I am mailing.They seal and close properly (for me). No holes, rips, or other flaws in the paper were discovered by me.(I attempted to purchase envelopes at Staples, but it was absurd. I was limited to purchasing items that cost 50% more rather than the less expensive ones. Then I understood that buying office supplies from Amazon would save me time, hassle, and money.Good envelopes at a fair price with prompt delivery.



Quality Park 12" x 15-1/2" Clasp Envelopes, Brown Kraft, Gummed Flap, 100/Box (QUA37810) Review:


These envelopes are excellent. They are a lot more durable than standard clasp envelopes. Due to the fact that I primarily utilize them to mail items out, this strength is also my greatest drawback when utilizing them. The envelopes weigh between two and three tenths of an ounce more than "regular" clasp envelopes because of the heavier material and superior craftsmanship. Since it is not a criticism of the product, I didn't deduct any stars, but if you use these to mail products, be aware that they are a few tenths of an ounce heavier than usual. This can change your shipping cost if you round up to the next full ounce.

I do wood art, and I ship my little single Wood-Crosses using these envelopes. Due to my slight OCD, I sandwich cardboard between grains of grain that are travelling in the opposing directions, thus enhancing the strength. These envelopes are profitable at 10 cents each. In order to pass on savings to my customers and still be able to pay all of my S
