Teeth Whitening Gel, Kastiny 4Pcs Professional Painless Teeth Stain Remover, Non-Sensitive Tooth Whitener Pen for Beautiful White Smile

Very good for the price

Don’t buy. Doesn’t work also the gel was actually like a paste, not sure if it was the storage or what. I used different brand before and actually it worked but not this one

One was empty, one worked, two were faulty and I couldn’t get the gel out!

Did not work

Loving the product so far, easy application. Beginning to see results.

Ormai ho perso il conto di quanti ne ho acquistati, veramente un ottimo prodotto, con costanza si possono avere degli ottimi risultati.

Bon article

Blanquea de verdad, tienes que ser constante, todos los días 20 minutos y lo notarás rápido.

Das Gel wirkt tatsächlich! Die Zähne sind zwar nicht heller geworden, aber mein Zahnfleisch hat innerhalb von Sekunden an gefangen zu bluten! Also, wenn Sie unbedingt bald wieder zum Zahnarzt möchten, dann genügen ein paar Anwendungen und Sie werden mit Sicherheit ein paar Termine brauchen, um wieder gesunde Zähne zu haben!

Non funziona i denti rimangono come prima !
