Yocan UNI Spare 510 Cartridge Magnetic Ring

Always be prepared with one or more extra magnetic rings for the Yocan UNI or the Yocan UNI Pro. Although one Yocan UNI magnetic ring is included in each of the products, it’s always good to have extras to make it quick and easy to switch between oil cartridges. These 510 thread oil cartridge rings are made using high-quality materials, so they’re durable and will last a long time. When installing onto your 510 thread oil cartridge, be careful not to overtighten, they just need to be screwed-on snug.
