I love Alliance Bubble Mailers. They are so handy to have around for mailing anything like pictures, CDs, DVDs, jewelry etc. The features that makes them so good are:
-The bubble wrap on the inside on both sides for cushioning items
-They come in many sizes such as 4 x 10, 5 x 10, 6 x 10, 8 x 10 and on up to as big as 14 1/4 x 20 inches
- They are made totally of recycled paper
-They come with lines are the front so you can write straight or you can get them with out the lines
- They are lightweight
-Supposedly they are water resistant although I have not tested this
- They have a sealing strip on them so no licking necessary
I have used Alliance Bubble Mailers for many different uses and have had no problem with them. I will say that I always put a piece a tape across the flap to make sure they stay shut but I do this anytime I am mailing something in a large envelope just as an added precaution.
I would also add I make sure the envelope is a little bigger than I need as the bubble wrap does take up room inside but this is not a problem especially knowing that what ever I am mailing will not get crushed on the way to the person I am mailing it to.
