Limited Run Valentines Day Themed Heart Shaped 510 Cartridge and Battery Pen Holder with Six Spaces.

Makes storing cartridges much easier and keeps them in an upright position to ensure the heating element of the cartridge stays saturated in the cartridge oil. This print has triple wall support and is a very sturdy plastic object. Empty cartridge not included.
 
Item measurements are below:
65mm long x 60mm wide x 18mm tall
 
Each of the 6 holding spaces are 12mm wide so they can accommodate most vape pen batteries of a small or medium size in addition to 510 Cartridges. They also hold the Arizer Extreme Q mouth pieces nicely.
