Quality Park Tyvek Open End 9 x 12 Inch White Envelopes 100 Count (R1460)

Great Stock

I purchased these envelopes for my tax business. I like to use a tyvek envelope when mailing important documents because they are waterproof and tear resistant. I think these will work well for me.

These are great for mailing fabric to my customers. Waterproof, sturdy and economical. I’ll keep purchasing.

If you need to ensure that your documents make it to their destination without any damage these are the envelopes you want. It's not a paper based envelopes but a plastic material. You can wet the envelope and it won't penarate what's inside. You can't rip it either unless you use a knife or scissors.

Wish I'd ordered one size up because they're not as roomy as I'd like. But that's my bad. And I don't really know how well they seal because I always tape them for security. Other than that they don't appear to be inferior to the well known brand, and a $ saver.
