My Battery - Media Case - As you can see this case opens fromthe top and the bottom with a divider between. I am able to start the day with this full of fresh supplies and as the day go on I replace and can keep used for fresh seperate and have it all in one place. Made of hard plastic it isreasonable water and dust tight. People claim it will float. Wit the translucent pallctic you can see which ites are in the case easly. It is even smallenough that it could fit in the pocket but would be a little bulky. A great little orginizer for all those little things.
