Review Image by Lashay Royale
I love these envelopes, they are such great quality. They are not thin. Their thick, crisp and the adhesive is very sticky as needed, the size is standard, and it's safe to place sensitive information in without worry. I don't ever want to run out.

    • #10 self-sealing envelopes are great for payroll
Size: 500 Count
I purchased these #10 self-sealing envelopes for payroll. These envelopes seal easily, they are the perfect size, weight, and durable. Any paper placed in these envelopes is very protected. I have purchased multiple times and love the durability, price, and design.
