2 Kitchenaid blender cups for K150 and K400 blenders for personal smoothies/protein shakes. Make yourself the perfect size drink without dirtying your full sized blender. Lightly used, work great. We have 4 and don’t use them that often and are trying to make some room in our kitchen. Blender cups are marked up to 16 oz but have room above that (probably 20 oz capacity)
