STABILO Write-4-all. Permanent markers for anyone who writes on CDs and DVDs in the office or at home, and for professionals such as carpenters, bricklayers or gardeners who need to write in extreme conditions and on unusual surfaces. The plastic nib is very durable and therefore writes clearly, even on hard surfaces. This has been tested on more than 1,000 materials, such as glass, plastic, photos, CDs, DVDs, ceramics, foil and metal. It even withstands extreme conditions such as cold, heat or rain. That is why the STABILO Write-4-all is also suitable for use in freezers or greenhouses. The ink dries quickly, is light and frost resistant, and waterproof. The STABILO Write-4-all is available in three line widths: superfine, fine and medium.
