Amazon Basics 10" x 13" Gummed Seal Clasp Kraft Mailing Envelopes, 100-Pack, brown

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: 5/5Right 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 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: 5/5The 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: 5/5When 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, 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: 4.5/5I’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: 4/5As 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. 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!

Not bad, seems strong enough. I tested and played with the seams a bit, moved the metal clips back and forth and I feel like this is acceptable quality. Compared to the ones I can find at the stores around me, this is far better value.

Good item at great price!! No need to pay for name brand this Amazon product is great.

These 9x12 Kraft envelopes are exactly what I needed for mailing documents, certificates, and small booklets. The material is thick and sturdy, so I don’t have to worry about papers getting bent or torn during shipping. The adhesive strip seals well and stays closed, giving me peace of mind that everything inside is secure.They’re also great for organizing paperwork at home or the office — the size fits standard sheets without folding. I appreciate the professional look and the durable feel of the kraft paper.If you need envelopes for important mailings or just better organization, these are a fantastic choice. Definitely worth the price!

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.

In a world where cardboard boxes get all the glory and bubble wrap thinks it's the Beyoncé of packaging, I present to you: the humble hero we never knew we needed — Amazon Basics Manila Mailing Envelopes.Let’s talk durability. These envelopes are so tough, I’m convinced they were forged in the fiery depths of Mount Amazon. I once accidentally spilled coffee on one — not a drop made it inside. My mail was dry. My soul was healed.Aesthetic? Oh yes. The rich beige tone screams "I pay my bills on time and also might be a secret agent." It’s a color that says, “I mean business,” but also “I own several succulents and alphabetize my spices.”Functionality? I mailed a handwritten thank-you note, two stickers, and a single Lego piece to my nephew. It arrived unbent, unbroken, and unchanged — unlike me after attending his fifth birthday party.In summary, if you're looking for a mailing envelope that says “I care deeply but efficiently,” look no further. These envelopes are the unsung postal patriots of our time.Buy them. Love them. Mail with confidence.(And maybe send your neighbor a passive-aggressive letter about their leaf blower schedule.)

They are what they are - great. Cost effective. I buy them in bulk here because they are too hard to find at any office supply store near where I live.

Just like the description! Basic and appropriate for mailing, The clasp gives one an extra sense of security.
