Staedtler Disc Marker Pen

The STAEDTLER Disc Marker Pen (made in Germany) is simply the best non-solvent, permanent medium tip marker on the market today which will not damage your DVDs and CDs. Ordinary felt tipped markers use solvents that can attack the protective coating on discs and ruin your data or music. (You can tell by the strong smell of the felt tip whether it's solvent based.) 

Features: 

• Instant dry
• Non-solvent - harmless to optical disc media
• Permanent 
• No-dry tip (tip will not dry out even when you forget to put the cap back on)
• Made in Germany
