Durable and stylish, the stainless steel shaker cup is the perfect way to blend your protein shake on your trips to the gym. The plain shaker cup is awesome for someone who’s always taking their shake to go. Available in two classic shades, black or white, the metal shaker cup is a good gift idea for men and women who like to work hard to obtain their fitness goals. Because the mixer cup is stainless steel, you get the benefit of it being BPA-free, in addition to its insulated double wall construction that helps with thermal retention. That way, your protein shake stays cooler for longer. The blender cup holds 25 oz. and comes with a ball and the standard leakproof shake mixer lid that helps prevent disaster when mixing your drink powder. The cheap-priced cup is a cool choice for someone who wants a classier shaker bottle, one that’s left blank and is less showy rather than your cup acting as a walking billboard as you prepare for your workout.
