Maximum durability: Made of stainless steel to provide rust resistance and shape retention for longterm use. It is designed to deliver a reliable, cup of tea every time without deformation. Enhanced tea enjoyment: Ultrafine filter design traps tea particles, preventing loose leaves from floating in the cup and resulting in cleaner, more stable infusion water. Convenient brewing accessory: Features a practical chain and hook that allow the infuser to be easily hung on the edge of cups, teapots, or kettles for convenient brewing. Easy maintenance: Advanced design enables quick cleaning after discarding tea leaves. It cleans easily, leaves no tea stains or impurities, and offers a practical yet aesthetically pleasing appearance. Use scenarios: At home with a standard cup: Place loose tea in the infuser, hang on the rim of a cup, pour hot water, and steep. Lift by the chain to remove the leaves when ready, enjoying a clean, wellinfused cup. Brewing with a teapot: Drop the infuser into a teapot to steep, then lift it out by the chain when brewing is complete to serve without loose leaves in the pot or cups. Office or casual settings: Hang the infuser on the edge of a mug or pot for easy access during a break, then rinse and reuse, maintaining a tidy brewing setup.
