Used this mermaid tail in the pool all the time as a kid. As you can see the edges are scuffed from in-ground pools with the concrete on the sides and bottom. The Monofin is the only thing that has a little bit of damage to it. The material is like a wetsuit it feels like so it’s really thick and durable. The mermaid tail just slips over the Monofin and has no damage at all. I can negotiate but be reasonable since this is a larger item and more expensive.
