We use only the highest grade USP PG, USP VG, and NicSelect Nicotine! We find that our customers don’t have the time in their busy schedule to measure out the PG, then the VG, and finally the Nicotine to make their DIY E-liquid – so we do it for you! Our Mixing Bases come premixed in 4 different sizes; 120ml, 250ml, 500ml, and 1000ml. But what PG VG ratio is right for you? We got you covered there too… We offer 100vg, 70vg/30pg, 50/50, 30vg/70pg. We offer 0mg up to 18mg – so we have something for everyone! Just add flavors, shake and vape!
