Theresa is an angle valve with an avant-garde design. Its two features make it an absolute must in the bathroom. Feature one, compared with traditional angle valves which have “rotating handles”, Theresa’s 90 degree on / off handles make the “switching” much easier. Moreover, it has two different colors to distinguish the hot and cold sides. Feature two, Theresa includes a net filter that can be easily opened with a coin. This net filter blocks dirt coming from the source, thus protecting the hoses and mixers from blockage and damage. This product has simple features, but with true concern for user experiences, ease of use and health.
