The Tick Pen is a convenient and innovative tool for detecting and safely removing ticks from pets at an early stage. Using fluorescence detection technology, it identifies ticks before they cause harm, helping to prevent health risks such as blood diseases and skin infections. When exposed to ultraviolet light (360-380nm), parts of the tick's surface reflect a fluorescent glow. If a tick is detected, the pen vibrates to alert the user. The side button controls the pen's threaded tip, by rotating and lifting the pen slowly, ticks are safely removed without harming the pet.
