Important Safety Note:
Mermaid tails are not buoyancy aids and are intended for experienced swimmers only. Swimming with a mermaid tail requires strong swimming skills, as your legs are held together. Always ensure proper supervision when used by minors. We recommend a minimum age of 8 years for safe and confident mermaid swimming.
