Hello guys, I am here to share a problem that has been troubling me from past week. The thing is that small amount of ink is seeping out from the area where the metal ring is there. If I don't use my hero 616 and the 221 for a day, then a small amount of ink leaks. I get ink stains on my fingers when I write with them.The leaking is more in case of the 616, but I want to fix the problem for both of them. Tell me what to do as soon as possible. Thanks in advance.
