Stabilo Luminator - the highlighter for all professional multi-highlighter users with design and brand aspirations. The Stabilo Anti-Dry-Out Technology protects against drying out for 4 hours, allowing for focused work. The non-slip grip zone provides a secure hold while highlighting. The Luminator has a larger ink reservoir than any conventional highlighter. The ink is dispensed evenly until the last drop. It also does not leak under changing pressure conditions, such as during takeoff and landing on an airplane. The ink level indicator allows for constant monitoring.
