SUMU is a cutlery series made of zirconia (zirconium dioxide). SUMU cutleries are 50% lighter than conventional metallic cutleries. They don’t interfere with the flavors of dishes as absolutely no metallic ions are released. Consequently, they never become the cause of metal allergies. You can focus on your sense of taste as the thin, silky finish of the zirconia tip ensures an exceptionally smooth feeling in and out of the mouth. The matte zirconia cutleries softly reflecting atmospheric lighting bring serenity to the dining scene.
