Mead #10 White Gummed Business Envelopes, 50 Count (75050)

I like and use these %2310 envelopes to receive correspondence back from clients. I fold and enclose them in outgoing mail. I prefer the lick and stick because the peel and stick sometimes pop open in route to me and all I get is an empty envelope. If the lick and seal is going to fail it does it right away, and you can tape it. On peel and stick may take hours to fail, and by that time it may already have been dropped off at a box. All seals on envelopes will start to fail after a few years of storage so I buy only what you can use in one year. You can't hold that against them, just buy in smaller quantities to avoid that issue.
