I am selling this item because I bought it as a spare but no longer need it. This is a flex edge beater attachment. It can be used with 4.5 and 5-quart mixers. It mixes while scraping sticky ingredients like cookie dough and cake batter from the bowl. This is a KitchenAid compatible product. Please see the photos for details. It will be shipped in a Yu-Packet Post envelope with waterproof packaging and simple wrapping. Compatible models: Artisan, Classic, Classic Plus, Ultra Power, Accolade 400, 90th Anniversary Glass Bowl, K45, K45SS, KSM75, KSM90, KSM95, KSM100, KSM103, KSM110, KSM150, KSM151, KSM152, KN15E1X,
