A sewing must have
I trace out my sewing patterns then use these envelopes to store my copies keeping the original whole. I've never had a clasp break and the construction is solid. I've been doing this for years so some envelopes are old but still great. Can also hold up to my puppy chewing a corner. Just the right size, excellent price and they fulfill all my needs. I have plenty of room on the back where I write notes from my project like changes I've made and the year I made the dress, what fabric I used and from where etc. I glue stick then tape the edges of my image of what's inside. These are a must have because when my daughter gets a compliment on something I've made her co workers can order one from me and I still have the original in tact so I can easily make a variety of sizes and it's far easier to grade for sizing. Nice and thick so even a sharpie won't bleed through it and they hold a lot.

Better quality 6 X 9" envelopes. Are they worth the price?
I use these envelopes for filing my records, receipts, insurance policies, etc. in an alphabetically labeled expandable file. Over past years, I purchased less expensive6 X 9" envelopes at Walmart, but their envelopes are thinner and do not hold up to repetitive use over the course of the tax year. I decided to upgrade this year by purchasing higher quality envelopes. I purchased two packs of 30 envelopes of the more expensive brand and also used some of the leftover Walmart brand for this calendar year. I will decide by the end of 2026 if the more expensive option is worth the extra cost.

Strong, Reliable, and Great for Everyday Use!
These clasp envelopes are what I needed for mailing documents and organizing paperwork. The kraft paper is thick and sturdy, not flimsy at all. The clasp is secure, and the gummed seal works well if you need extra closure. They’re the perfect size for letter-sized papers without folding, and the pack of 30 is great value for the price. I’ve used them for both personal and office tasks, and they hold up really well. No tearing or issues with sealing. Great quality and reliable. I will definitely repurchase when I run out!

Good Value
Good value for the money. Clasp closure secured contents well. I use to sort previous year’s receipts for tax purposes. Very useful and can store in a banker’s box.
