Hollowness, tinniness or high pitched frequencies can all be reduced or eliminated with the use of this fantastic filler. Just place some in the bottom of your case in the desired locations, seal it up and you are good to go. Each bag contains approximately 5-7g of Polyfill which will be more than enough for 2-3 keyboards or more. Show more
