12 x 15 1/2 White Self-Seal Envelopes 500/Case

These white self - seal envelopes don't need moisture to seal. Just peel off the tear strip and you're done! The tear - off strip keeps the adhesive dust - free, giving them a long shelf life. They're made from sturdy 28 lb. paper stock.

Using these envelopes is super easy. You don't have to worry about getting them wet to seal. Just peel the tear strip off and press to seal. Keep them in a dry place to maintain the adhesive's quality. If you're storing them for a long time, make sure the area is clean to prevent dust from getting on the adhesive. There's no special maintenance needed, just use them as you would any other envelope.
