I carry my elfbars in my pocket or backpack, this causes the inlet orfice to mug up with fluff and debris, so I designed this simple tubular case to hold it with a cap for the mouthpiece.

Notable design features are a pinhole in the base to allow air to escape on insertion and a cut to slide the elfbar in and out. The cut also allows to use the vape without completely removing it, just make sure the inlet is on that side.

Disclaimer: While the holder in itself is not NSFW, it goes without saying any smoking paraphernalia is to be used only by adults.
