Safety material and food safety: The boiled egg timer is made from foodgrade unsaturated polyester resin and thermal paper and is food safe. Marks left by grinding on the bottom are normal and do not affect use. Heat sensitive color change: Place the timer in the pot with the eggs in boiling water and monitor the colors as the eggs cook. When the timer color reaches the scale indicated by the label and the reference line, remove the eggs. Ingenious design for clear indication: The timer works by absorbing heat and using a colorchanging pattern layer, allowing you to easily and intuitively gauge the degree of doneness and ripeness at a glance. Effective egg timer for reliable results: Enjoy eggs the way you like them without guessing. The colorchanging indicator lets you boil eggs soft, medium, or hard with consistent results every time. Practical use scenarios: Quick weekday breakfast: Boil a few eggs and rely on the timer to achieve the desired doneness without watching the pot constantly. Batch cooking for the family: Simultaneously boil multiple eggs and use the timer to ensure uniform results for salads, sandwiches, or meal prep. Meal prep and entertaining: Prepare eggs in advance for balanced proteins on the menu, with dependable doneness suitable for variety of dishes.
