The Staedtler Textsurfer Classic Highlighter has a large ink reservoir for extended highlighting performance, making it deal for marking text and coloring larger areas. 

Highlighter Features:

• Water-based ink
  
• Ultra-soft chisel tip can create markings between 1 and 5 mm wide
• Twist cap for easy opening
• Fast-drying
• Does not smudge writing or printed text
  
• Airplane-safe: automatic pressure equalization prevents ink from leaking at high altitudes
• Black color is a hidelighter that covers up text and lines. Text will still be legible on the original document but becomes illegible when the document is copied.

Listing is for 1 Textsurfer Highlighter only; each color can be purchased separately.
