We purchased many boxes of these to use for our summer water play day. While they were nice to use for a quick backup if you run out, they did not last, AT ALL, and they were teeny tiny balloons. If you don't plan on using the balloons right away, and I mean within 10 minutes, you might as well not purchase these. Also, most of them popped coming off of the straws that hook to the hose. It's an awesome idea...but it doesn't really "tie off" at the end like it says. It has a small rubber band that goes along the bottom that allows water to leak out of.
