I have a Visconti Homo Sapiens Crystal that shows some sort of disturbance to the plating on the clip. The cap and trim rings seem unaffected.
Although it looks like something is happening under the plating, I thought maybe something was on top of the plating. I tried cleaning with a silver polishing cloth, Windex, ammonia water, etc but nothing has touched it. So I am thinking it may be under or in the plating.
I have contacted Coles of London (US Distributor) and am awaiting a response, but I suppose they will want me to send it in.
In the meanwhile, has anyone experienced this condition on one of their pens? Does anyone know how much a clip replacement costs if it is not covered under warranty (I am not original owner and do not have original purchase receipt).
