A classic for beautiful writing. The ballpoint pen is not just a constant companion in everyday work life. It is used to jot down information and capture thoughts. Therefore, it is quite frustrating when it no longer functions properly. With the replacement refill from Caran d'Ache, you can ensure worry-free work. It is easy to insert and prevents unnecessarily long interruptions. Additionally, it allows the pen to be used longer, which is good for your wallet and beneficial for the environment. A special ink paste makes this tool particularly effective. A robust ball at the tip makes the item a reliable all-rounder. The black color is pleasantly understated. An empty ballpoint pen can easily become a nuisance in important moments. So always keep enough replacement refills on hand.
