A holder that fits a variety of lung capacity testing devices. This will hold/fit the yocan plus XL, the yocan evolve, the yocan armor, and the utilian 5...and probably a lot of other ones as they all are based on certain battery packs. It also has a spot for a butter knife. May or may not be useful as an actual butter tray.
