So we bought a logi Pencil for school, and there is a couple of issues with it. Firstly, the end for the charger came off. It still charges and all, but the rubber was a nice touch. Secondly I’ll be writing and it’ll start writing in a bunch of dots. I think this might be related to the third problem, which is the tip is flattened. I notice one side is better than the other to write, which is the side with a less flat end. Anyway to sharpen the tip again, or is it stuck like this forever?
