Vintage tea ball, tea infuser. I have not tested this older vintage tea ball for silver content and will sell it as silver plate. It is an elegant older vintage piece that dates at least back to circa 1920. It is in very nice condition with the lid snapping tightly closed. The ball measures 1.5'' in diameter. It suspends from a 4'' chain. This estate find will make a quaint addition to your next tea party table setting.
