Hello:
After a long time keeping my shells in packets in a bad way, I'm putting
them now in a nice cabinet, but I have found that several ones have a white
powder on the surface. I think it's the famous "Byne's disease" but I'm not
sure.
Can you tell me if it's this disease and how can I avoid it and recover the
affected shells?
Thank you
