Gaining popularity in the early 19th century, tea infuser balls were seen in every respectable English home. Today, tea infuser balls are used in many homes around the world to simply brew a cup of tea without needing to strain the tea afterwards. The Winco STB-5 2 inch tea infuser ball is durable enough for commercial kitchen use, but modern enough to be used in just about any cup of tea in the office or at home.
