Polylin Professional Whitening Cubes | Sponge Whitening Brush with Split Polyphosphoric Acid | Made in Japan

From the Polylin Serious Whitening Series, these Professional Whitening Cubes are a convenient, travel-ready solution for maintaining a bright, stain-free smile. Each cube contains a sponge toothbrush infused with Split Polyphosphoric Acid, a patented whitening ingredient developed by Regentis.

The fine-cell sponge efficiently removes coffee, tea, and tobacco stains without damaging enamel, while forming a protective coating that helps prevent future discoloration. Each cube is individually packaged, making it perfect for on-the-go care, business trips, or as a thoughtful small gift for whitening enthusiasts.

Key Features

• Triple whitening effect: combines Split Polyphosphoric Acid, Sodium Metaphosphate, and 4Na Pyrophosphate for visible brightness.

• Easy to use: simply remove the sponge from its package and brush gently around stained areas.

• Portable & hygienic: single-use cubes are individually wrapped for cleanliness.

• Coating protection: prevents re-adhesion of stains, leaving teeth smooth and polished.

• Peppermint freshness: gently eliminates bad breath while whitening.

Note: The sponge may show visible discoloration as it lifts stains from the tooth surface — proof of its effectiveness.
