The only thing I can comment on is:
We do have a ferw 3ml samples available, but they are dwindling and we probably will not have them much longer.
The 100% VG line has a higher water content, to give the same consistancy of PG
*take this as you will...as some think that matters for such and such, but no one has
officially complained about it after receiving it.
Also, people with severe PG allergies have not had any reactions to the 100% VG line
