Have you guys ever had a cartridge like this? Does it require a special pen? I ask because on my leaf buddy it doesn't pull. I'm thinking it's not connecting properly with the coil. There are ridges that makes it different from other carts I've used Sent from my iPhone using Grasscity Forum
The brass and glass one? I have one for a standard threaded end pen. Sent from my SAMSUNG-SM-G891A using Tapatalk
Nah, not that. It's weird because every standard thread I've had has a flat bottom when you look at the part that comes into contact with the coil, however this one is slit Sent from my iPhone using Grasscity Forum
