Rinse blades thoroughly after use, dry and store dry to prevent corrosion. Handle blades carefully to avoid injury. If the blade must be cut in half for shaving with an interchangeable blade knife, break it lengthwise before removing it from the wax paper to avoid injury and splinters. After use, return to the wax paper and disinfect briefly before using again. Replace regularly to prevent skin irritation (blade life can vary between 2-5 uses depending on blade and thickness of beard hair). Collect blades in a blade waste container until final disposal (do not dispose directly in household waste!). Do not share with other people to prevent infection. Keep out of reach of children. Do not swallow (risk of injury!).
