Enjoy your favorite loose-leaf tea on the go. This cleverly designed cup has a leakproof top with a built-in magnetic ball that suspends the infuser basket above the hot water. To release the basket, rotate the ball 180° and the tea drops down to begin steeping.

• Infuser basket holds tea until you're ready to steep it.
• Magnetic ball controls release of basket into cup; gold side of ball indicates when basket is released.
• Leakproof lid has sipping spout that snaps closed.
• Made of BPA-free zinc and double-wall borosilicate glass.
• A Williams Sonoma exclusive.
