Unique design keeps the cup steady. Double-walled and graduated. Drink without spilling. The unique ergonomic design increases leverage of the hand and aids in raising the cup to the lips without wrist motion. The thumbs-on grip reduces the possibility of spilling due to trembling. The cup is double-walled to protect hands from heat or cold.
It holds 8 ounces (237 ml), leaving 1 in. (2.5 cm) of free space above the liquid to reduce spillage. Liquid ounce and metric measures are marked inside. Top rack dishwasher and microwave safe.
