Working principle: Uses centrifugal force to mix egg white and yolk evenly without breaking the shell. More hygienic: Simple and fun. The entire process keeps the shell intact, and the egg contents do not come into contact with air, ensuring a cleaner result. Picky eating solution: For children who dislike egg whites or yolks? This tool helps blend the white and yolk evenly inside the shell. Once cooked, the egg becomes a uniformly mixed golden egg. Easy operation promotes better nutrient absorption. Food grade material: Soft food-grade silicone pad provides 360-degree protection for eggs, safe and effective without damaging the shell.
