These mailers have traveled far and wide through the post office UPS and FedEx and have always arrived in perfect condition. The seal holds up great and the bubble layer gives that added protection.
My purchase of a package of seal bubble mailers was coupled with the purchase of a quick drying pen. While the mailers were fine the quick drying pen was the best as it was dried up when I first tried to use it. A total lose a pen with dried ink had to be tossed. I will watch quick drying pens in the future but shouldn't have to as they should not be put on the floor for sale!!!
super easy to use because it is cushioned you don't need to add anything and because it has an adhesive seal you don't need tape...it just makes life easier.
