I purchased this from Amazon US a few years ago and imported it personally. The teeth part has started to spin freely. Therefore, I am selling it as junk. (The following is a translation and reprint from Amazon) Easy Access: You can add ingredients for thick blends like nut butter and baby food without removing the lid. Personal Blender: With this kitchen blender, you can make single-serving smoothies, shakes, and salad dressings. Easy to Clean: Use the dedicated Twister Jar Spatula to scrape out all the smoothies and protein shakes. Clear Markings: This blender can be used to measure ingredients when making shakes and smoothies. Blend Safely: Our dull kitchen blender blades crush ingredients and prevent injuries.
