20-ounce capacity (Note: measurement markings only go to 14 ounces)
Patented mixing system uses 316 surgical-grade stainless steel BlenderBall wire whisk found only in BlenderBottle brand shaker cups
Wide mouth makes it easy to add mix scoops and liquids, and embossed markings measure both ounces and milliliters; rounded base for thorough mixing
Screw-on lid creates leak-proof seal, and secure flip cap with SpoutGuard keeps the mouthpiece clean; wide loop top for easy carrying or attaching keys
The quality of the cup is very good. I like this big water cup because I am a sports enthusiast and this kind of water cup always brings me convenience!
