    keeps your extra batteries secure and close at hand for extended basement larp sessions

    Nifty little carrier for 6 cells. Keeps them secure and quiet, much better than using zip lock bags like i used to. Just gotta be aware not to loose the foam insert when opening the storage container as it isn’t secured to the lid. Overall a handy little product.
