After trying this product, I can confidently say these are the perfect eco-friendly solution for water balloon fights. The balloons are easy to fill, seal and biodegrade quickly, causing no harm to our environment .We had a blast playing with these, and at the end of the game, we didnt have to worry about the clean-up. However, the price may seem a bit high for some, but it's worth it for environmentally friendly toys and games!See full review
