Ball shaped tea Infuser (5 cms diameter) with a sturdy long push handle. The infuser including the extra-fine perforated mesh is made of high grade stainless steel, which is nickel plated. Perfect & practical medium to steep all loose leaf teas, herbs, flowers and spices which expand & need a lot of room for steeping. Tea ball is large enough to allow optimal water flow to unlock the best flavor of large, medium or fine tea leaf without a teapot. The retractable long handle design is easy to open and use and simplifies the process of tea brewing. The 0.5mm holes are best to reduce tea debris floating into your mug. Designed to fit in any cup. The fine 0.5mm holes of this mesh ball do not allow tea leaves to escape into the cup. If you enjoy drinking whole leaf teas this infuser is a perfect means of brewing loose teas even at work or while travelling.
