After researching the hell out of where to buy these balls, we ended up buying from these guys as they were USA based, and always answered their phones & emails super quick! They weren't the cheapest, but you get what you pay for. We made the mistake of buying our first set from China which lasted about 2 weeks! We purchased 24 balls from Bubble Bump Soccer. 12 adult sized and 12 child sized balls. The help we got from these guys was great and they gave us all the info needed to get a jump start on setting up Bubble Bump Soccer in our area. We're only working this business on the weekends, but it won't be long until we switch to full time. What a great way to make money and having fun too! Thanks, Tyler.
