I just saw a reference in a post in another subforum to a Chinese e-liquid manufacturer named Feellife. Since I had never heard of them I checked out their website. Among their products is something they call E-Solid.
I quote:
Fascinating! I don't know whether it would be the best or the worst viscosity for delivering e-liquid to the atomizer, but it sure is different.
E-solid is new reserched products,it has many advantages compared to e-liquid. Easy to carry and transport, easy package, easy to use and long time working. Product rights and patent belong to Feellife Bioscience international.Co.,Ltd
