It's just a pill buttle from pharmacy, sanded to matte. Also use aluminum foil tape to make a cone and insert into bottom to reflect the hotspot toward the side. There you have it, cheap diffuser cone for your novatac.
Besides just keep in pocket I don't really know easy way to carry it. You can keep stuff in there, but nothing heavy or it'll crush the aluminum cone. I don't EDC it thou. The light is so diffused with this thing it's more like a mini lantern than flashlight, so not very useful for urban daily use.
