Based upon a revolutionary new production technique, Hidersine Reserve21 Violin rosin is a light-coloured, medium-hard formulation using only the finest ingredients. Among the ingredients are WW-grade Brazilian resins and British beeswax, which when carefully combined deliver a fabulously low-dust, high grip playing experience.
This unique recipe helps produce an articulate, tonally balanced sound which lends itself to ensemble playing in particular. 
Each Reserve21 Rosin is presented as a 30g cake poured onto a beautiful, hemmed microfibre cloth encased within a custom velv­eteen drawstring bag. Each bagged rosin is packed into a Reserve21 individual box, with 8 pieces within a master carton.
Hidersine Reserve21 Rosin is made in England, United Kingdom using an Artisanal process of hand-mixing and hand-pouring.

“I enjoy using Hidersine Reserve21 during a busy concert season. It’s a great, affordable and practical rosin that is smooth and has a good duration, so you don’t need to constantly reapply. I definitely recommend!”
