The Stabilo Write-4-all is a permanent marker designed for labeling CDs and DVDs in both office and home settings. It is also suitable for craftsmen such as carpenters, masons, and gardeners who need to write under extreme conditions and on unusual surfaces. Its writing capability has been tested on over 1,000 surfaces, including glass, plastic, photos, ceramics, foils, and metal. The plastic tip is more durable than conventional markers, allowing for clear writing on hard surfaces. It works reliably under extreme conditions such as cold, heat, or rain, making it ideal for use in freezers or greenhouses. This marker is excellent for gently labeling CDs and DVDs, dries quickly, is waterproof, and resistant to light and frost. Additionally, it offers high protection against drying out without a cap, and the cap can be attached to the end of the pen.
