PREMIUM ROSIN WITH PERSONALITY: Magic Rosin is an exceptional quality and professional grade rosin that offers unrivaled grip and delivers a clear, complex tone. Unique designs transform Magic Rosin into beautiful music-making tools! | CLEARLY SUPERIOR: The crystal clear, glassy appearance is a testament to the purity of our instrument rosin. Our recipe uses purified pine resins, free of additives like oils, waxes, dyes, and metal fillings that are often used by other manufacturers. | MUSIC STUDENTS & PRO SOLOISTS: They can all agree on one thing; no other rosin comes close to Magic Rosin! 2-3 quick swipes across the bow hair is all it takes, saving you time on reapplying! The #1 choice for string players from students to soloists! | TWO FORMULAS: Our popular formula for string players is the 3G, which is a grippy rosin created for the violin and viola. Ultra formula is grippier than 3G, recommended for cellists, bassists, or any advanced string player seeking more grip and "pop". | FROM JUILLIARD TO YOUR BOW: The Magic Rosin company was founded in Minneapolis, MN in 2010 by Sarah West, a Juilliard-trained professional cellist. Our rosin now hails from East Northport, NY and is guaranteed fresh. Likely poured the same week you order!
