Why do my sharpie pens dry out so fast?

Sharpie pens can dry out quickly due to factors like exposure to air, improper storage, or frequent cap removal. If the cap isn't secured tightly after use, ink can evaporate, leading to dryness. Additionally, storing them upright with the nib facing up can contribute to quicker drying. To prolong their lifespan, always cap them tightly and store them horizontally.
