I am disappointed with this product, on the one hand the quality of the rubber is mediocre and what störtest me the most is that the colors shown are not included in the box. It is not black, not white, not dark blue in the box. Everything just pink, purple and orange tones, 2 greens, 1 light blue, only the striped rubber are 2 blue. All in all I have to say hands off, it is more reasonable the colors individually to buy.
