Our engineer is asking what is the diameter of your lead? If it is smaller than 10.51+/-0.15, plus the gap we already designed on this pen, there should not be any lead scratch, may I suggest you to check the lead is centralized? Do you prefer to send over some defective samples so we can help to review with?
