Needs to have a more durable seal would recommend to a friend if it was more durable. Please fix this I only shop at Staples and [...] so I am a loyal customer and will not change but this one product needs to be improved.
These worked well for calendars and letters and small packets. The adhesive strip was easy to remove and the envelopes seal well as long as they are not "full". If there is a thick catalog or anything comparable inside then the seal doesn't do so well.
Adhesive strip is about 1/2 inch wide. Flaps started to peel up as I was stuffing them had to go back and reseal all of them with packing tape. Better off spending more money and not getting the house brand.
