If you are looking for a great blue raspberry-flavored e-liquid, we have a couple recommendations:
1. Blue Raspberry Jolly Rancher by Boondock Vapes
This is a great blue raspberry flavor, and their e-juice line if one of the better priced out there.
They use a 70/30 VG/PG mix, which is a nice mix. it is not too thin, and does have a decent throat hit at 12mg.
2. Blue Meth by Island Time Vapors
This is a nice subtle blue raspberry flavor, inspired by the Snow Cone flavor. It is a subtle blue raspberry with a hint of cotton candy.
