Marker Cali 4 mm

The Marker Cali 4 mm features an innovative ink that starts completely transparent and gradually becomes visible over several hours. Upon exposure to UV rays—whether from sunlight or artificial sources—the ink transforms into a deep dark brown, creating durable, nearly permanent markings. This makes it an ideal tool for discreet labeling and secure identification where subtlety is essential. Danger H336 May cause drowsiness or dizziness. H412 Harmful to aquatic life with long lasting effects.
