Our ball pit kept increasing in size. We have 3 bags of balls, in great condition. I was a bit of a hygiene freak when the kids were younger and have hand wiped each ball when they have been put away. None are dented.
Was in toys r us today - Each bag in toys r us is now RM140!!!
Also, we have a pool that has a hole, we used that as the last ball pit. You can have it if you have the patience and time to patch it!
