I keep some of my shells in drawers in a wooden cabinet.
Each shell is in its own compartment which I have made from wooden partitions.
One drawer can have a maximum of 200 small compartments (about 3,5 cm x 3,5 cm) but normally my shells are bigger so one drawer includes less than 100 compartments.
You can see a photo of one drawer here:

That's very useful because I don't need to buy plastic boxes for all shells.
The wood should be well dried - atleast I haven't noticed any signs of Byne's disease. The humidity and the temperature are quite low here in Finland throughout the year.
I'm considering to buy a second cabinet for my shell collection but that could be metal.
Does anyone know brands which have same kinds of metal cabinets - including a possibility to make all kinds of compartments to the drawers?
Best regards, Markus Niiranen
