It is as described. The adhesive doesn't taste so bad when you lick it like some other brands. The only thing I thought was a little odd was the adhesive did not run along the entire edge of the flap. It only had one small strip of adhesive in the centre of each side of the flap so when you actually close and seal, there is a little bit of gapping that could allow small items (like a corner of a piece of mail or paper, etc.) to get stuck inside. Other than that, it is your average envelope.
Next time I will buy a self-adhesive envelope - I just like the efficiency and lack of licking. I'm always afraid of having a paper cut on my tongue whenever I have to lick an envelope flap for some reason.
