Can someone tell me what this is?

Hey guys, I got this with a Provari I bought in the classifieds and I have absolutely no idea what it is or what it is worth. From what I have read, it is some sort of kayfun tank? I was thinking of selling some stuff in my parts bin and I came across it. Any ideas? Thanks in advance...

I got this as well.....carto tank?

There are no markings on it as far as I can see.

The first tank says "by Leo". This is a telescopic tank. GV Telescopic Tank

The second tank appears to be the "slim tank". Tanks

You can put the Killer 705, a submersable rebuildable atomizer, in these tanks. Killer 705 (Septero)
