The Nano Bottom Coil Clearomizer - Brand NEW! For those that want a smaller bottom coil feeder clearomizer, we introduce the NANO. While a lot of people love CE3's there were some issues that we heard over and over again. The syringe was too much for most, and seemed people ran in to burn hits a little bit more than they would like. We took the general concept of the CE3 and added a few improvements to make it work better, perform better, and best of all...no Syringe required! The 510 Nano holds 1ml of e-liquid and they are SUPER EASY TO FILL! Simply screw off the cap drop some e-liquid in, and screw the cap back on and vape! Easy as 1-2-3! NOTE: When filling avoid getting e-liquid in the center tube THE CAP MUST BE SCREWED ON WITHIN 40-60 SECONDS OF BEING FILLED TO AVOID LEAKAGE.
