Adhesive Gel Pads These gel pads are made of high-quality hydrogel. Easy to use: simply remove the two protective layers and attach to your belt. SERVICE LIFE Under normal conditions, the gel pad has a service life of 30 uses when properly maintained. REPLACEMENT INDICATORS Replace the gel pad when it accumulates dirt, the surface dries out, or loses adhesion to ensure optimal performance. PRECAUTIONS Ensure the skin is clean and dry before application. After use, store the gel pads in a sealed bag to prevent drying. If the pad loses stickiness after several uses, lightly dampen it with water, gently remove excess moisture, and wait 5–10 minutes for full absorption before use. As gel sheets are consumable items, replace them when effectiveness diminishes after opening. PACKAGE DETAILS Each package contains 2 pieces.
