Yocan Uni Pro Box Mod Replacement Magnetic Ring

related:3
The Yocan Uni Pro Magnetic Ring is one of those tiny accessories you don’t think about until the day you misplace it—and suddenly your whole setup comes to a halt. This little adapter is what keeps your cartridges clicking perfectly into the Uni Pro, turning what could be a wobbly fit into a clean, magnetic snap that feels way more satisfying than it has any right to be.

It’s simple, sturdy, and does exactly what it needs to: maintain a secure 510-threaded connection so your cartridges stay put without any guessing or fiddling. Pop it on, drop your cart in, and you’re back to smooth sessions with zero frustration. It’s the unsung hero of the Uni Pro—never flashy, but absolutely essential.

If you’re the type who likes carrying multiple carts, swapping flavours, or just keeping everything running like-new, having a spare magnetic ring handy is never a bad idea. It keeps the Uni Pro feeling fresh, functional, and ready whenever you are.
