The hole or ring of the egg opener is slightly wider than a regular teaspoon. The inner edge is smooth and not sharp, which will not scratch your table and will ensure the freshness and authenticity of the eggs. Easy to Use: This egg opener allows you to open the shell easily and smoothly in seconds. To use, simply hold the top cup with one hand, lift the handle with the other, lift and hold it, and then release it 2-3 times. The shock wave on the cup body will cut the shell, leaving a perfect cut around the egg. Dimensions: 10.5 x 3.3 cm. Perfect for all eggs, regardless of size (please allow slight size difference due to manual measurement). It makes delicious egg desserts and takes up very little storage space. High Quality: Made of high-quality stainless steel, this egg cup is safe, durable, rust-proof, and has a long service life. Its inner wall is smooth, not easy to retain food residue, and is easy to clean. Practical Kitchen Utensils: These practical kitchen utensils are perfect for cooking soft-boiled eggs, hard-boiled eggs, or raw eggs, providing you and your family with a healthy breakfast. They can not only be used to make custard, pudding, and cupcakes, but also as a small green plant or for other purposes to meet your different needs.
