Comes with a small drip tray for resting the tea strainer. These tea infusers for loose leaf tea are very practical and convenient. WIDE APPLICATION: Suitable for all types of loose tea, especially for medium to large tea leaves, such as chamomile tea, Ceylon tea, raspberry leaf tea, etc. These tea infusers are ideal for tea lovers.
