The longevity of the ink depends on the pen, but most are about 6â8 months. If the pen dries up, you can try heating up the ballpoint part with hot water in case the rollerball is stuck. Another option is to keep the casing and purchase a refill for the pen. You can find ink refills online in the office supplies section of Shoplet.
