The buoyant RSVP Float My Boat Tea Infuser stays at the surface while a stainless steel mesh tea ball - like an anchor - hangs down and steeps your tea. The whimsical boat is sized for teapots or mugs. After your tea is brewed to perfection, place the boat and tea infuser in the drip cup, which is designed to look like rollicking waves. This is the perfect accoutrement for any tea lover.
