Samuel Kolstein Double Bass Rosin - Hard, Made in USA

Kolstein's Hard double bass rosin draws on more than forty years of development for the professional player's needs: rich tonal quality, even adherence, extremely low powdering and a smooth, easy bowing feel. Every cake is produced in the Kolstein workshop in the USA under exact product control, using precisely measured premium ingredients poured into alloy-lined wooden moulds for uniform hardening, then cured for a fixed period to avoid thermal cracking. The harder formulation suits bassists who prefer a firmer grip profile, particularly in warmer conditions.
