Listing is for 1 Tea Infuser with Black Obsidian Stone. These are STOCK PHOTOS. Because they are natural stones, characteristics such as size, color and shape will vary. These tea balls are ~ 2 inches in diameter and will hold at least 1 - 2 teaspoons of tea with room for the leaves to expand - perfect for a single (small or large) mug of tea! The stones measure about 1 inch and the chain is approximately 3 inches in length. Our 304 stainless-steel tea ball features fine mesh and closes on the side to secure the tea leaves. The crystal hangs on the outside of the mugs to balance the the tea ball. Tea balls are easy to use and clean! Just add your tea, lock the hinge to close, and steep as directed for your tea. To clean, please hand wash your tea ball while avoiding exposing the wire-wrapped stone to excessive or prolonged moisture. We suggest hand washing these and drying them thoroughly. Do not put in the dishwasher, the crystal will not be happy.
