Developed in Sweden

by professional orchestra musicians, Rosin Saver is a revolutionary storage device designed to keep rosin feeling as fresh as the day it was made. Through use of a patented 2-way humidity system your rosin will maintain ideal playing properties regardless of weather, temperature or venue.

Rosin Saver fits neatly into your bow or instrument case and prevents evaporation of the natural waxes and oils in rosin that play a vital role in how your bow sounds and feels on the string.

  • Airtight Lid

    Keeps in humidified air with a laboratory grade styrene-butadiene rubber seal.
  • Durable Canister

    Tough double-wall canister that fits conveniently into instrument and bow cases.
  • Humidity Packs

    Patented 2-way humidity packs preserve rosin freshness and ideal playing characteristics. Our long-lasting packs can last a year or more with normal use. 2 packs are included with each kit.
  • Reusable Silicone Cup

    The silicone cup is designed to replace the paper cup on some bass rosins. Because paper quickly degrades in high humidity, paper should be removed prior to inserting rosin into silicone cup. Roll down to use. (included with Rosin Saver BASS)

How it works

the Sweet Sound of Science
the Resin
Oil-rich compounds known as oleoresins are separated from wood fibers and refined to varying degrees
the Rosin
During manufacture, rosin makers often blend even more oils and waxes with the resin to attain a recipe with a rich, smooth sound
These natural oils and waxes evaporate readily from the rosin surface leaving behind a layer of dry, dusty powder
The stale rosin surface comes into direct contact with your bow hair giving a slippery feel and thin, gritty sound
By thoroughly saturating the air surrounding your rosin with water vapor, the oils are forced to stay where they belong
Rosin Saver
Maintains a consistent humidified environment keeping rosin feeling fresh, consistent and reliable
