Exactly what you would expect
I picked up this 100-pack of Amazon Basics Clasp Kraft Envelopes because I needed something reliable to ship comic books I was selling on eBay. After comparing prices, this was the best deal per envelope I could find, so I decided to give them a shot and hoped the quality would hold up.They turned out to be exactly what I needed, sturdy, well-made, and just what you’d expect from a standard mailing envelope of this type. The clasp and gummed seal both work well, and theyāve held up great during shipping. Perfect for basic mailing needs at a great price.The size fit what I expected, the adhesive seal seem to work just fine.

Great Value and Versatility
I recently purchased the Amazon Basics 9 x 12-Inch Clasp Kraft Envelopes, which come in a pack of 100, and Iām thrilled to share my thoughts after using them for various projects over the past few weeks. If youāre in need of a reliable, sturdy, and reasonably priced envelope option, keep reading for a detailed review!Quality and Material: 5/5Right out of the box, I was impressed by the quality of these kraft envelopes. Made from a solid paper material, they feel sturdy and durable, which is essential for mailing important documents or protecting items inside. The classic kraft color gives them a professional and clean look, whether Iām using them for business or personal correspondence. The gummed closure is reliable; it sticks well without requiring a lot of moisture, which is always a plus.Functionality: 5/5The size of these 9 x 12-inch envelopes is incredibly versatile. I primarily use them for sending documents, but Iāve found them useful for a myriad of purposesāstoring artwork, organizing paperwork, and even for presenting gifts. The clasp closure at the top is a standout feature. It allows for easy access to the contents without the hassle of tearing the envelope open or worrying about it accidentally coming undone during transport.Value for Money: 5/5When you break it down, the 100-pack is a fantastic value. With the cost-per-envelope being much lower compared to purchasing smaller packs at local stores, itās an economical choice that doesnāt sacrifice quality. Given the variety of uses, I find that having this many envelopes on hand saves time and money in the long run, as I always have them ready for when I need them.Performance: 4.5/5Iāve used these envelopes to mail documents and even thicker items like small booklets, and Iām pleased to say they hold up remarkably well. I once sent out a batch of invoices and received no complaints about damages, which is a definite win in my book. One minor caveat is that, while the envelopes are sturdy, be careful not to overload them. If too much weight is added, the seams can split, but this applies to most envelopes.Environmental Considerations: 4/5As someone who is increasingly mindful of environmental issues, I appreciate that these kraft envelopes are made from recycled materials. However, I wish they were made from 100% recycled paper, which would elevate their sustainability credentials. Still, the kraft paper gives a rustic, eco-friendly vibe, which I find appealing.Overall Experience: 5/5Overall, my experience with the Amazon Basics 9 x 12-Inch Clasp Kraft Envelopes has been overwhelmingly positive. They deliver on all fronts: quality, versatility, and value. Whether you’re mailing documents, organizing your office space, or looking for a reliable envelope for gifts, these envelopes are by far an excellent choice.I would highly recommend these to friends, family, and anyone in need of a dependable envelope solution. Iām already planning to stock up on another pack, as I want to ensure I never run out. If youāre on the fence about purchasing these envelopes, I say go for itāyou wonāt be disappointed!

Great price, great product!
Why pay more for 100 envelopes? Great price and they stick well. Color matches pictures on description. Great to be able to stock up on these mailers, and wont run out of them anytime soon. Perfect for business, or personal use and they stay sealed well, very secure.

Better value than name brand envelopes!
As a teacher, I use a lot of these envelopes. With the amount that I use, I was looking for an option that was more economical. Well, I like these envelopes better than the name brand! The quality of the envelopes are top notch with the thickness of the material. The size of these envelopes are large (9×12) giving lots of room inside. Not only do these envelopes use a metal clasp, they also seal with a very strong adhesive. Color is as pictured.

Sturdy, Reliable, and Great for Everyday Use
These Amazon Basics clasp envelopes are exactly what I needed for mailing documents, storing receipts, and organizing paperwork. The kraft paper is thick and durable ā not flimsy like some cheaper brands ā and holds up well in the mail or in storage.The metal clasp is secure, and the gummed seal adds extra protection when I need to fully close the envelope. Iāve used them for everything from tax forms to kidsā school papers, and theyāve never ripped or come apart.Simple, no-frills, and super dependable. Great value for a bulk pack ā I always keep a few in my drawer now.

Needed something to keep each year of tax stuff together. Was using a 9X12 envelope but it was getting tight with all the slips and receipts and a printed copy of the return. I like the clasp as I can open (hopefully never) and close as many times as necessary.Oddity with the shipping – 100 envelopes shipped loose in an Amazon box. Not really a problem – just expected a package or shrink-wrapped bundle – took off my socks and made sure the count was correct. š

…Pretty hard to screw up an envelope…I like that these have metal clasps, easy to open and close which keeps papers from falling out without having to lick and seal it, a nice touch!
