I recently purchased the Amazon Basics 9 x 12-Inch Clasp Kraft Envelopes, which come in a pack of 100, and I’m thrilled to share my thoughts after using them for various projects over the past few weeks. If you’re in need of a reliable, sturdy, and reasonably priced envelope option, keep reading for a detailed review! Quality and Material: 5/5 Right 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 I’m 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: 5/5 The size of these 9 x 12-inch envelopes is incredibly versatile. I primarily use them for sending documents, but I’ve found them useful for a myriad of purposes—storing 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: 5/5 When 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, it’s an economical choice that doesn’t 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: 4.5/5 I’ve used these envelopes to mail documents and even thicker items like small booklets, and I’m 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: 4/5 As 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: 5/5 Overall, 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. I’m already planning to stock up on another pack, as I want to ensure I never run out. If you’re on the fence about purchasing these envelopes, I say go for it—you won’t be disappointed!

Great price, effecient, seals well.good quality

We buy these envelopes often, They are durable and the quality and size are perfect for our office use. and the work well with what we need to use them for. I wish they came in different colors.

Even when one goes paperless, there will be papers to hold onto, temporarily or permanently. Hard copies of important documents (e.g., LWT and RLT), temporary holds (e.g., tax returns), and personal correspondences, along with purchase receipts, insurance and medical payment documents, among others, tend to accumulate in no time and might be hard to sort out when needed. This is where the clasped envelopes have helped a lot, especially in situations when quick retrieval is necessary. Hard copies of my will and trust in these envelopes are stored in the bank safe deposit box, and PDF copies are kept in my hard drive. Hard copies of e-filed tax returns and supporting documents are kept in envelopes for each year. Different insurance policies and payments are stored in separate envelopes for each year. The troublesome accumulation of store receipts that have refundable items can be organized into envelopes either by date of purchase or vendor, and discarded after the warranty period. The utility of these sturdy and inexpensive envelopes is limited only by your needs and innovations.

Envelops themselves are a good product and as expected. One downside for me; they arrived in a traditional brown shipping box and you must store them in the same box instead of a clear plastic storage sleeve or some such.

Worked perfectly. Highly adhesive. Great value for your money. Easy to seal. Great weight for mailing.

Just what I needed at an amazing price. The quality is great, I’ve only sealed with a clasp as I use this to hand to borrowers for their loan documents, not to be mailed out. If you have to use these to ship, I suppose it would be fine. They are the average size thickness and again, worth the price.

These save space and keep small items in an enclosed storage space

For some reason calendars in Canada do not come with an envelope to mail. Used these envelopes to make envelopes to mail calendars abroad. I couldn't purchase this envelope size at my local Staples.

Amazing for holding important papers for giving important papers to customers good durability, good quality, easy to open and close. Sizes was perfect for what I needed it for.

Llego bien y los sobres de buena calidad.

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. ;-)

...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!
