Try to find an environmentally controlled case - this can be
expensive but possible and set to around 45% to 55% Relative
Humidity.  I have found that bowls of water are an easy short-term
solution but quickly evaporate and need replenishing; larger vessels
start to cloud or become alga-contaminated within a week or two.

Alternatively some suitable dressing agent to prevent protein
delamination works quite well: there are many such on the market and
the one that I have used is called Bollmann Ultra-soft which
partially-rehydrates animal skins for taxidermists, making the skins
more pliable, and should be available via taxidermy supplies.  In
Spain they use a fluid called Complucad but I have had no success in
trying to order from their website and subsequently have no
experience for this fluid. With all good wishes,
