These genuine Buffalo milkshake cups are a great addition to the Buffalo Milkshake Mixer. Designed to fit perfectly, these 0.9Ltr cups help to maximise the visual impact of your shakes, with attractive pink, green and blue colours supplied. Each cup is made from a strong, BPA-free Tritan material, meaning they are both food safe and highly durable. They're easy to clean too, as each cup can be simply washed in a professional dishwasher.
