My meers are always out, in a rack, 2 or 3 in the ash tray, always ready for use and never stowed in the case. I smoke meerschaums almost exclusively when at home, they do not travel with me, so I keep them readily available. The fitted cases are stored in a drawer should I have use for them.
I would suggest that if you have racks which sit on shelves, move them towards the back so that when accidents do happen the pipe merely falls over and does not suffer a drop. I've smoked meers for many years and while bits have been replaced only one pipe suffered major damage. I was lucky, as it was a favorite, in that a band salvaged it.
