Live Hash Rosin. Here comes the new school! The legendary Runtz quickly became a household name thanks to a list of celebrity and hip-hop endorsements. Mix in the doughy, full-bodied Cake Crasher, and this party is lit. The bold vanilla hues of cakes, meet the tart-sugary touch of Runtz. This Live Rosin was selected by Erick Khan and cultivated and manufactured by our friends at Terp Mansion.
