The color doesn't rub off rings, and they are sturdy, and strong.
Arrived on time and in good condition.  It is a fun toy to play with. I ordered 3 different combinations of colors. Mainly  blue with mix of pink and silver,  A mainly pink with mix of blue and silver, and 3rd one  equal mix of all three. Favorite is mix of all three.  It would be great if there were more color choices to chose from . I like that the rings move more freely with little noise.
