OK, yes. Akishibu Project’s latest promotional video looks like an advert for toothpaste. “Eien White Teeth” IS a promotional vehicle for the Okamura group, who manufacture dental products and oral care products. Sparkling smiles glisten aplenty, but what really works for this PV is the girls of Akishibu Project. They make the best of the brushing choreography and present a great song.
