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.
Foot fatigue is a common condition that occurs after you stand or walk for long periods of time. The foot muscles become overly tired and cramp, causing the sufferer to experience pain and begin to limp.
There are many common causes of foot pains, such as blisters and corns. There are also less common causes of foot pain, such as sciatica and osteomyelitis. Foot pain may cause unsteady gait and/or limping. Treatments for foot pain depend on the particular cause.
