YOCAN MOD - UNI Universal Portable Box Mod
Yocan UNI box mod is the  first universal width and height adjustable box mod that will work with all sizes of universal 510-threaded oil cartridges! The Yocan UNI Box Mod features everything you came to love about Yocan products: ease of use, affordability, functionality, practicality, and now protection for your valuable oil cartridge.
The UNI Box Mod uses a patented design that offers two types of adjustments so it can be customized to fit all oil cartridges, regardless of size and length. The first adjustment is to the opening size to accommodate any width cartridge. The key here is the UNI's adjustable knob located just below the lip of the cartridge chamber. Rotating the knob left or right causes the opening to grow or shrink to properly hold your cartridge tightly in place. The second adjustment is for the cartridge height, which uses a lever to adjust the height of the cartridge so the mouthpiece is properly positioned for easy access.
