There are several ways of storing rocks and minerals specimens. Some prefer to have them visible, other prefer to have them secured in boxes. Personally, I prefer to have them stored in a box, so they don't get dirty with dust, so I decided to build a simple wooden box. It is a simple rectangular box with small boxes inside like drawers that are pulled from top. Dimensions of the main box are 40cm length x 20cm wide x 25cm height. There is space for about 4 drawers inside. I have organized the smaller specimens into paper boxes, although the larger specimens are loose. You can see a small video of how it works to open and pull the inner drawers: https://www.youtube.com/shorts/LhDBVJ7s5Vk I have used this style of box to store minerals but I can be used for any other kind of collectible.
