With OXO's Twist & Pour Salad Dressing Mixer you can serve and store salad dressing in one convenient 14 oz./1 3/4 cup capacity container. It has a leak-proof and airtight design which keeps dressing contained while mixing and fresh during storage. The non-slip ring is easy to grip and twist even when hands are wet, and turns a bi-directional mixing blade for maximum agitation of thin or thick dressings. It also has a wide opening for adding a range of ingredients and convenient measurement markings for easily following recipes. The Mixer is dishwasher safe and BPA free.
