Grimmer - when you say you 'mix' the flavors, are you mixing them in separate bottles or just by adding different flavors in the carts and letting them mingle in there?
I have smaller mini bottles from 3ml - 5ml. I have made a really good clove juice using several different flavors..1/2 clove..1/4RY4...1/4vigina or marl what ever is your favorite tobacco flavor.
a good mint vape 1/2 mint.....1/4 RY4.....1/4 clove...
I even do fruit delights 1/3 banna ...1/3 strawberry ...1/3RY4 or mint
or coffee breaks I call it 1/2 coffee or capo 1/4 chocolate and 1/2 of 1/4 RY4 and vanilla
I use same mg of each flavor....keep that in mind when you mix.
