Sinmoe 12 Pieces Inflatable White Beach Ball Bulk Summer Solid Swimming Pool Floating Blow up Ball DIY Paint Craft for Boys Girls Hawaii Luau Birthday Beach Graduation Party(16 Inch,White)

They did not deflate and had great durability

Some of them blew up easily, some were SUPER hard and not all of them would stay inflated.

Great product, just hard to blow uo

Absolutely ridiculous return!!!! The inflatable beach balls were NOT round, yet Amazon is making me take them into a store in order to return instead of being able to print a label and drop into a ups Dropbox. Won’t be making many purchases from Amazon any more!!!

One arrived with a hole. Most of them didn’t hold air for one day.

This is a nice set of beach balls. I went looking for a set of these after yet another ball got popped by the kids. These are decently made beach style balls, good for the pool, or, surprise, the beach.If you plan on using these for a decoration (30th birthday, perhaps?), I would recommend inflating them well prior to the event. The are all vacuum packed, which means that they initially have a fair number of wrinkles. If that matters to you, fill them up and let them sit for a while.Now, if you're like me and just looking to have something to play with, they're good out of the bag.My one nit: they have inconsistent valves. What do I mean by that? First one I inflated, no challenge, filled right up. Next one, I had to blow really hard (while pinching the valve). Next one, no problem... (so wasn't my lungs!) So far, I've inflated about half of them. I would say about 30% of them were harder than they needed to be.In all, though, it's a decent set of beach balls. Nothing fancy (and does not include patches). But a good set to have around -- and now I have spares when someone inevitably lands on one. Sigh.
