We used these for movie night in the pool. We watched Jaws and made shark attack drinks.I bought the sharks for a drink accessory and they worked exactly as expected! I didn't have any problems with them leaking, and they were completely hollow, which were big plusses. They looked really cool and I was really happy with them!Great for shots or cocktails but 2 or 3 were defective unable to hold liquids.I spent quite a bit of time looking for hollow sharks to fill with grenadine and finalize my shark attack drinks! Look no further - I did the research for you - these work. Disclaimer in that probably 4-5 of the sharks were a bit leaky, but the majority were perfect.Grand daughter loves these. Plays with them everyday in the pool and bathtubNice garnish for party drinksOriginally purchased for Shark Week snack decorations, these are now a favorite water/bath toy for the younger kids. They're well-made, the plastic is thick and would be perfect to use for drink chasers, etc.Product was not only shipped fast, but very well protected! These sharks are actually larger than I thought, which was a really good surprise - They measure about 5 inches each, and the box comes with sharks of two different colors which are perfect to give them as favors in my son's birthday party. Thank you so much, love the product~!
