The bubble mailers I stock are Featherpost which are a great quality envelope, and slightly bigger inside than the equivalent Jiffy size.

I also stock Arofol CD Mailers, which are perfect for up to two CDs, and much easier to load than other eqivalent sizes as they are widest at the flap side.

Both brands of bubble mailers are strong mailing envelopes of laminated Kraft paper with a bubble lining to cushion your items.

They have a peel and seal flap, which is covered with backing paper that peels off easily.

You can use them as they are or add extra padding to give extra protection.

I use bubble mailers to speed up my packing and to get a light and professional looking package.

As you can see from my Ebay feedback, my own packages are well-wrapped and secure.
