HIGH-QUALITY MATERIAL – Made from thickened PC material with high hardness and an integrated soft food-grade silicone pad. Offers good elasticity and provides 360-degree stable protection for eggs. Safe, effective, and helps prevent damage to eggs. SIMPLE AND FUN – Shakes the egg white and yolk evenly inside the shell without cracking it. After boiling, creates a uniformly mixed egg. EASY TO USE – No power required. Pull the cord multiple times to initiate rotation. Mixing takes only about 10 seconds. Pull the cord quickly and fully release it after each pull for automatic retraction. SAFETY AND HYGIENE – The entire process keeps the shell intact and sealed. Egg contents do not come into contact with outside air, helping maintain cleanliness and safety. DESIGNED SIZE – Approximately 76 x 76 x 170 mm. Ideal for mixing yolks and whites in standard-sized eggs. Best suited for uniformly sized eggs. Not recommended for oversized eggs, duck eggs, or eggs with thin shells, as they may break during use.
