Staples QuickStrip EasyClose Envelopes
Not only do these new envelopes taste terrible when you lick them but then they dont even stick. I have to use Scotch tape to seal them and that tastes a little better but still it doesn't stick that well after licking. Maybe a cough syrupy flavor would taste better and stick better too My cough syrup bottles are all very sticky and they are difficult to open so I gues...

AMAZING Envelopes!!
These are the most incredible envelopes I have ever purchased! So WHITE. And the QuickStrip EasyClose Self Seal is so EASY it's just the bee's knees. I have never been so happy about a purchase as I have about these wonderful envelopes. Thank goodness Staples requested this review or I would never have had the opportunity to gush about these beautiful envelopes.

Be wary. It doesn’t seal.
Pre sealing feature doesn’t work very well.
