Our products are made of eco-friendly materials (biodegradable resin) and we developed a toothbrush with an eco-friendly certificate for the first time in Korea. In particular, the eco-friendly disposable toothbrush has toothpaste added to the brush and does not require separate toothpaste. Environmental pollution of other disposable toothbrushes and shavers greatly used beyond imagination in bath houses and lodging facilities in Korea has become a severe problem.
