Personalized Soccer Balls for my son

My son is very interested with Soccer ever since he was 2 years old. We enrolled him in a Summer Camp when he turned 3. It was something he really enjoyed and now that he is 6  , he plans on trying out with Soccer classes again. To start off, I am planning to get him personalized soccer balls just like what I saw online. I am pretty sure he will enjoy playing with his own personalized ball. Since green is his favorite color, I would definitely get him one in green. I am really excited for the day that he would start in Soccer classes again , it's something that we both look forward to.
