Hello everyone, I recently bought a Marsh 99 and it works really well, but I have an issue with the nib. When I let this marker sit overnight it seems to dry out and won't write properly unless I prime the nib again, I've used this a fair bit over the last 3-4 days and this still happens. I'm using a very thin ink in this marker so I doubt it's the ink. How would you fix this issue? I know these take a while to break in, but I feel like it would be good to go by now. Any help with this is greatly appreciated.
