Dear Conchlers,
I have a simple question regarding shell storing. I store my shell
collection in drawers made of white plastic, under normal indoor
environmental conditions, and no direct sunlight. The temperature is not
particulary warm or cold (I live in Italy), but I don't know the percentage
of relative humidity - please note that at the moment the drawers are in my
bedroom... Well, sometimes when I touch my cowries they appear coarse, like
dried, but this condition diseappear when I clean them with a soft cloth (I
have to rub them...).

What do you think about? Just dust? Any suggestion re. the right
temperature and relative humidity? I'd like to control environmental
factors ....

Thanks.
