Nasal wash bottle designed for gentle sinus rinsing with saline solution. Squeeze-bottle design with an angled nozzle tip for comfortable, controlled use. Helps clear nasal passages and relieve congestion. Reusable, easy to clean, and simple to use at home. Suitable for adults and older children (please follow standard nasal rinse usage guidance). I kept this general and avoided specific medical claims (like treating sinusitis or allergies) since it's a health-related product — just describes its intended use.
