I accidentally dropped my Mars Matic 0.5mm and noticed that maybe I broke the needle. I was having a hard time writing with it so I tried to clean it, and while cleaning I accidentally bent the needle part. After all the trouble that I experienced I manage to straighten the needle very carefully.
Right now it's working fine but I need to shake it rigorously. I am planning on buying a new one because of the hassle of using it but there is also a side of me that says I should not buy a new one.
Is there any other way that I can fix my pen? It's slightly bent now but by shaking it rigorously it can still write.
