I got quite a few copic markers that have gone all mucky. There's a crust formin on the brush nibs and no amount of refilling has helped. The ink has gone really... Funky. It doesn't seem to even have the right texture that it usually has. Like it's gone mucky?
Has anybody ever brought copic's replaceable nibs? There's an art store here, but it's hella expensive. I could find them online for cheaper, but was wonderin if anybody has come into the same problem I have.
