Leklai is a mysterious treasure found in the deep mountains of Thailand and Malaysia, locally known as เล็กไหล (pronounced "Lencha"), with the English name LEK LAI (Flowing Iron), also called Leklai. It is regarded as Sacred Iron, possessing boundless power. Leklai is a rare and uniquely shaped natural metal mineral. Each piece of Leklai is unique, with no two pieces being identical. Its color changes with the magnetic field and deepens with maintenance. Some Leklai are soft and white phosphorus-like; exposing them to water and sunlight gradually removes or changes the phosphorus.
