I have several that remain a mystery. When I started
vaping,I mixed some different juices adding this and that. SOME GOOD SOME BAD.
I put them in a drawer with sticky notes saying what they are made of. Of course through time the notes came off. I vaped a few of these and found one I'm nuts about. Now the problem is figuring out what was in it. That may sound simple except I have around twenty small bottles and about fifteen lost the sticky note! Look forward to hearing your reviews.
