So this thing is 18500. I can use my brass Nemi tubes to make it a 18650?I have a couple of genuine poldiacs and they are excellent. Slightly finicky to set up but once you do the button is one of the best.
Nemesis tubes have the same threading so you can get different looks with coloured Neme tubes if you want. The pieces of tubing you use is dependent on the clone, two of the kick sections plus or minus the tiny thin ring.
