"Relax Tooth-Brush Smoker Hard" appears to refer to a specialized toothbrush designed for smokers, focusing on deep cleaning and stain removal. It likely features:

Hard bristles – For tougher stain removal from tobacco and nicotine.

Anti-stain properties – May include abrasive or activated charcoal elements.

Gum protection – Possibly designed to minimize gum irritation despite firm bristles.

Compact or ergonomic design – For better reach in smokers' stain-prone areas.

(Note: "Hard" bristle brushes may not suit everyone, especially those with sensitive gums. Dentists often recommend soft bristles for most users.)
