The logo needs to be a very simple clean logo in white, with a symbol that can be used with or without the logo. 
 
It will be printed on a variety of colours which is why it needs to be white. 
 
What I mean by that is, the name Nicotech or the symbol could be used on small items like electronic cigarettes, batteries etc whereas the symbol and the logo could be used on the box together. 
 
The images attached is a typical example of what the e-liquid packaging and starter kits will look like, so I need a logo to suit. The symbol could be an abstract image of smoke or liquid.
