Bouncey Ball Swap

My son wanted to get involved in a swap. So here goes...He stops at EVERY vending machine to get a bouncey ball everywhere that we go!!! So we thought it would be fun to swap some and see what other varieties there are. Please send 5 bouncey balls of any shape or size to your partner. This swap will be very inexpensive since they do not weigh a lot and only cost a quarter! Would be fun to write a small bit of info about person sending them; like age,# of bouncey balls collected if any, ect.
