#10 self-sealing envelopes are great for payroll

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.
