  6. Variations: There are different variations of clasp envelopes, including some with expandable gussets to accommodate thicker contents and others with various types of paper material, such as kraft paper for a more rustic look.

  7. Availability: Clasp envelopes are readily available in most office supply stores, stationery shops, and online retailers that offer office and mailing supplies.

  8. Cost: The cost of clasp envelopes can vary depending on factors like size, quantity, and customization. They are generally affordable and cost-effective for mailing important documents securely.

User questions & answers

Question: Can I put a six page, 10” x 13” document in these envelopes
Answer: Thank you for your interest in the Mead clasp envelopes, these are made in the U.S.
Question: how many envelopes are there in a pack
Answer: I'm sorry but I can't tell you. I have a brother QL 700 label printer and print all of my labels and return addresses, then stick them on the envelopes. The manual for my laser printer does not say anything one way or the other about printing addresses directly on envelopes with metal clasps, but I would not want to risk it myself.
Question: where are these envelopes made
Answer: I really don't know. The envelopes are standard clasp envelope type of paper. The envelope itself eas fine. It was the clasp that was bad and had to reinforce the bottom of each with tape. But we were putting bulky items in them and not flat stuff which might have contributed to the problem.
Question: we need 15 1/2 x 12 do you still have this size
Answer: Yes the 10 by 15 can hold this amount of sheets, also, it fit perfectly fine in my 12 1/2 by 9 1/2 inch envelopes. I would put extra tape on both bottom and top sealing area to make sure it is reinforced. Good quality envelopes and great price.

User questions & answers

Question: country of origin please
Answer: Hi, Donna. I do not know. But I'm confident (a) there is no chance they'd use expensive brass, and (2) if they were to use it, it was say so on package.
Question: How do I change my order from 4 boxes of envelopes to 2 boxes
Answer: It depends on the thickness of the magazine as well as the weight of the magazine. Anything published before 1970 was composed of different materials making them heavier.
Question: Can I send this envelope without the picture being bent
Answer: The clasp is gold.
Question: Are these 28lb or 32lb envelopes
Answer: These Manila envelopes says 8 ounces each, but they seem a lot lighter, more like 4 ounces each. Hope this helps!

Question: Can a magazine with dimensions of 11 x 9 fit into the 10 x 13 envelopes
Answer: While this is a sturdy envelope, there is no guarantee that something won’t happen during the mail process to bend it or that it will get dented in some way.
