Our tester pen is composed of high-quality and durable drop-proof insulation, ABS, and 45 steel, which ensures safety while using. In self-check before use, please hold the pen tip with one hand and touch the tail with the other hand. When the light is on, it means the tester pen is normal and has sufficient power. No light indicates that the battery needs to be replaced. The pen is designed with a bright LED light, which is also an obvious cue when used during the day.
