The Yocan UNI Magnetic Ring is a magnetic connector designed and engineered specifically for the Yocan UNI Box Mod. Compared to other magnetic rings, the Yocan UNI Magnetic Ring offers a raised connection unlike others like the Yocan Handy Magnetic Connector that has a flat dimension. The Yocan UNI Magnetic Ring allows the UNI Box Mod to accommodate a wide variety of 510-threaded cartridges for wax and thick oil. Like other magnetic connectors from Yocan, the Yocan UNI Magnetic Ring was designed to make reloading, removal, and replacement of atomizers easier and more convenient. All you need is to screw the 510-thread of the atomizer or cartridge to the connector and let it slide in the Yocan UNI Box Mod’s chamber.
