COMFORTABLE DESIGN: The nose clip fits the contour of the nose, gently fixing the bridge of the nose, ensuring comfort and waterproofing. Effective Waterproof: This nose clip prevents water from entering your nose, allowing you to focus more on swimming and breathing for more comfortable swimming.

If the nose clip accidentally falls into the sink, the color is easy to spot.
