Ableware 745720000 Arthro Thumbs-Up Cup Without Lid by Maddak

Functional and lightweight for people who have decreased grip strength, wrist pain, hand deformities or need to keep the wrist in a neutral position. 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" (2.5 cm) of free space above the liquid to reduce spillage. Top rack dishwasher and microwave safe.
