[POWERFUL FUNCTION]- Whether the blade is sharp and the juicer cup is sealed is very important for us to buy juicer cups and blades. The 24oz Ninja blender cup produced is exactly what you want. We use stainless steel blades with a thickness of 2.4MM. The 7-fins base can provide more cutting power for the blade, which can easily shred fruits and even nuts. Both the blade and the mouth of the cup have a sealing ring, so you don't have to worry about the juice splashing out during use [SHOPPING TIPS]- Please confrim whether your juicer has the installation position of 7 fins before use, and the diameter of the blade is 4 inches.
