These indoor pickleballs are sturdy, bright and come twelve to a package. They are made for sports performance. Ready to go as soon as you get them out of the package. Easy to use and perfect for indoor activities as well as outdoor. We used them outdoors as well to play baseball with our plastic bats with the Grandkids. They love playing with them. They are easy to hold and easy to throw around. Lightweight and bright color makes them easy to round up too.
