🥚 Heat-Sensitive Colour Changing Technology The red egg-shaped timer reacts to water temperature while boiling, gradually shifting colour to clearly indicate soft, medium, and hard-boiled egg stages. No guesswork or manual clock timing required. One-Size-Fits-All Boiled Egg Helper Place the timer directly in the pot alongside raw eggs during boiling. Marked clear labels for Soft, Medium, Hard doneness to make ideal runny yolk, jammy-centre, and fully firm boiled eggs every batch. Durable Heat-Resistant Food-Safe Material Made of heat reactive non-toxic resin, fully safe for submersion in boiling water. Resists fading, melting or cracking through repeated daily stovetop egg boiling cycles. Eliminate Overcooked Grey-Ring Egg Yolks Stop the common issue of ugly grey sulphur rings around hard-boiled yolks. Remove eggs the moment the timer hits your target colour stage for smooth, bright yellow yolks with perfect texture. Compact & Easy Care Design Egg-shaped compact form fits any boiling pot size. Rinse clean with cool water after use, no complicated cleaning needed; lightweight for drawer storage, retail blister hang packaging ready for shelf merchandising.
