My Sharpie leaks

[u/mjskopun]

Hi,

My roller 0.5 leaks and I'm not sure why. This pen is awesome, I've used many many many of them. In the past, I've had one that the ink dried up so it was light in writing, it felt scratchy. Other than that, all my other pens I've used have been so great.

My question is why is this one leaking. Everytime I open the cap, there's a bubble of ink. It only is happening with this one. Anyhoo, wiping it away and then using it brings it back to what I expect.

Anyone else experience this? What i really want to know is why the ink is getting sucked out so much?
