Pop-rock band GReeeeN, which consists of four dentists from Fukushima Prefecture, will release their new oral care products nationwide starting September 1st.

These are not your typical promotional items. There’s a fine line between normal artists goods and this: a lot of research actually went into these. As all the members act as dentists when they are not promoting, they have been developing this new line of products to incorporate all of their knowledge.

Products include portable mouthwash, Y-shaped dental floor in mint flavor, antibacterial inter-dental brush, and an ultra-fine toothbrush with rubber grip for plaque removal and easier polishing.
