Pratt KAJ-2 Self-Seal Kraft Bubble Mailer, 8.5" x 11" (100 Pack)

What is this?

Bubble mailers (8.5" x 11") 

Why did I buy it?

I started selling my old DVDs back in the day, but needed a way to ship them. I would buy these bubble mailers from Staples in packs of 10, but find myself going through them too quickly and at too great a cost. Enter Amazon... they sell bubble mailers in packs of 100 at a price dramatically cheaper than Staples - it was a no brainer. 

I like keeping some bubble mailers on hand because I find that the 8.5" x 11" size can accommodate many different types of items, some of which I would typically use a box for - winding up with a greater weight and cost. These are light and slim, perfect for USPS 1st Class mail under 1lb.
