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 prevents damage to eggs. SIMPLE AND FUN – Shakes the egg white and yolk evenly inside the shell without cracking it. After boiling, creates a fully mixed egg. SIMPLE OPERATION – No power required. Pull the rope multiple times to initiate rotation. Mixing takes only about 10 seconds. Pull the rope 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, ensuring cleaner and safer results. PERFECT SIZE – Approximately 76 x 76 x 170mm. Ideal for uniformly sized eggs. Not recommended for oversized eggs, duck eggs, or eggs with thin shells, as breakage may occur during use.
