I prefer these over others because the envelopes are self adhesive and they work. So many I have tried do not stick very well but these work perfectly!
The staples brand number 10 peel and stick envelopes are so easy to use. Before I used the peel and stick envelopes I had to use a moistener sponge to close the flaps of the regular number 10 envelopes. Now I just pull the quick peel strip and close the envelope for mailing. Mail outs are easier and much quicker now that the sponge moistener is no longer needed ands all that has to be done is to pull off the quick strip and fold the self-sticking flap over to close the envelope. I love these number 10 self sticking envelopes! They make my day much easier.
