contact seller and no good response, them contact amazon service and they respond ...
first never received, contact seller and no good response, them contact amazon service and they respond inmediately and mediate with the seller who then send me a second pair, it did arrive but it was a very poor quality material fits very small for my 3 years old boy (size was 2-4 years) and they just dont work at all, my son can take them off and on whenever he want .  waist of money and time.
