Fineliners are amazing inventions. They have all the boldness and smudge-proof colours. But, they have a significant drawback – they dry out easily. But, of course, you can revive them with a few simple steps. However, remember that re-moisturising the pen takes more than just dipping in the water. To revive them, you need to use rubbing alcohol. Also, if you’ve left them too long in the water, you can try injecting back the water into the pen depending upon the pigment shade.
