Hi everyone!
Don’t hate me, but the Dead Rabbit R works for me. I’ve been vaping it for 3 years. When I bought the tank, my package included a 6.5ml bubble pyrex glass and a 2ml, or 3-4.5ml? plastic one (I can’t remember right now, but its volume is small), but I know it came with different sleeves. Well, unfortunately, I dropped my kit and my large bubble glass broke. What could be its replacement? Because I can’t really find one. Or if anyone has one, I’ll gladly take it. I’d even settle for the 5ml straight sleeve, but the 6.5ml would be the best. Currently, I have to refill it quite often 
Hugs to everyone!
