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!

They're envelops and they work fine

I hate running out of clasp envelopes. The Amazon Basics are very good quality, perfect size and an amazing price.

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 — not flimsy like some cheaper brands — 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. I’ve used them for everything from tax forms to kids’ school papers, and they’ve never ripped or come apart. Simple, no-frills, and super dependable. Great value for a bulk pack — I always keep a few in my drawer now.

Faithful old standard at a great price. Good quality - not the heaviest, but that makes it cheaper to mail. If you need heavier, get the PO one that is now $12, but includes shipping

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.
