Banana OG x Thin Mint Cookies The only ingredient in our UltraPremo Live Rosin is our single-source Crystal Water Hash. We press 90-119 micron trichome heads for this grade of rosin because they contain the most terps. All our rosin is first-press only. We carefully choose our press temps and pressures to create the best rosin we can that’s light in color, loaded with flavor, and has an ideal consistency. Store in the freezer for long-term, fridge for short-term, keep on the counter if it’ll be all gone in 1-2 days. Let your jars warm up before opening to prevent condensation.
