Misleading description. It is NOT 100% silicone as stated in the description. It passes the "pinch test". When squeezed, the silicone turns white, indicating the presence of fillers. It seems that most (all?) of these hemispherical shapes on Revain are cheap quality and falsely advertised. I've tried a few as I couldn't find any branded products that I trust.
