This is our Chiton Slim 7x7 Inch Sleeve for hard drives and DVDs. It works perfectly for Apple's USB Superdrive. It can handle any external drives from 6.5-8 inches long and about 6.5-8 inches wide, as well as other accessories. These stretch a bit so they are nice and tight around items on the slightly large end of the spectrum.
We're not big fans of zippers so we designed these to fold over the end instead of enclosing with a zipper. We also added an accessory pocket so you can stow other stuff as needed.
What you get:
1 Chiton Slim 7, 7.5 x 7.5 inch neoprene drive sleeve with accessory pocket
