My Therapy Balls have an odor. Is this normal?

Our solid therapy balls are a natural rubber product that does sometimes have a scent, which fades over time with use just like a new car, new carpet, new sneakers. Some may notice this scent while others do not, it is not immediately “erasable” but will dissipate. We recommend just giving them a good rub down with a towel as that sometimes helps accelerate the evaporation of the scent.
