I have some gift cards for amazon so i wanted to try to get soem PG there. they sell lots of PG, but its all for a cigar humidifier, heres exactly what it says:
"Madelaine cigar humidifier SOLUTION PG Propylene glycol pre-mixed"
I dont know if this is good, am i looking for USP grade PG? or is that only for the VG? im just so confused. any help would be good, thank you
