I keep mine in a cologne box in my closet.It's a box with a lid that slides on and off.The question is that I use my windows as much as possible.I live in Tx and it gets humid.Right now the humidity is 90% and I have my windows wide open.Is this bad for them?Is their something special to put them in?A freezer bag or something?I wonder if the humidity thing is overrated?I think constant extreme temp change would cause the problems,not humidity.If it's sealed tight(factory sealed) I don't see why you can't keep them stored in water if you wanted.What do ya'll think?Or preferably....know?
