Qleen is a 100% Bamboo wood, hygiene system which includes a 15-month supply of toothbrushes. QLEEN toothbrushes are made from sustainable bamboo and nylon bristles. Qleen also comes encased in a luxurious box set, each containing a year's supply of brushes designed with exceptional attention to detail. The case has vent holes in each compartment to ensure it breathes and airs out completely but, small enough so nothing gets in.
