SOLADEY N4 Manual toothbrush type Normal TiO2 solar panel (YUKI Snow) (Tip P) semiconductor/Built-in (Shiken)

[SOLADEY N4 brushes teeth with light and water] SOLADEY N4 removes dirt from teeth using water and light, allowing you to experience sufficient brushing power even when brushing by hand. [Built-in TiO2 semiconductor] "Minus electrons" generated by the action of a photocatalyst that reacts with water and light disrupt the balance of dirt attached to the teeth and increase brushing power. This TiO2 semiconductor uses SOLADEY's (Shiken Co., Ltd.) proprietary technology, which has manufacturing patents in 12 countries around the world. [Built-in solar panel] A solar panel is built into the toothbrush body, and the indoor light energy when brushing is applied to toothpaste. Another "negative electron" from the solar panel leads to ideal brushing through the action of a semiconductor photocatalyst. [Tip point bristles] The brush used in Soladay N4 is "compact head tip point bristles." The chevron-shaped tip allows detailed brushing to the grooves of the back teeth where there is a lot of unpolished areas, between the teeth, and behind the front teeth. *Can be replaced with your favorite brush (sold separately) [Made in Japan/Toothbrush's first Eco Mark certification] Soladay N4 is a product that is produced domestically and takes advantage of Japanese industrial technology. In addition, the Soladay series is the first Eco Mark certified product as a toothbrush with a replaceable brush part. *1 pack of replaceable brushes (4 pieces). Also, if you have an implant, please consult your doctor before use. SOLADEY N4, which brushes teeth with light and water ①TiO2 semiconductor Adopts TiO2 (titanium oxide) photocatalytic technology that cleans dirt using light and water. By reacting to indoor light and sunlight, it generates e- (negative electrons) and approaches stains on teeth. ② Conductive rubber Designed so that you can touch the conductive rubber no matter which direction you hold the bristles as a conductor that transmits e-. The design naturally invites you to use the pen grip for more detailed brushing. ③Replacement brush method Adopts "tip point bristles" that fit between teeth and clean even the crevices. You can choose a spare brush from a variety of lineups to suit your tooth alignment, tooth size, and brushing method. ④Solar panel The necessary e- is generated when light hits the panel part. The solar panel that reacts to indoor light can be used as a light in your room or bathroom, and the waterproof structure allows you to clean the entire product even in rough water.
