2 sizes : small and large comprising each:
- 1 Horizontal base with 8 to 14 holes ( according to size ).
It is provided with a label holder to help with identification of the minerals, trilobites, ammonites, urchins, bivalves, vegetals and other dinosaurs.
- 3 Vertical stems.
Those stems fit in the holes according to the shape and size of the mineral/fossil and according to the angle one wants to obtain. The stems support vertically the weight of the object, thus totally resistant to crushing. Each stem can be shortened, if required.
- 1 4th cross-stem.
It is strengthened against ben ding and swivel on itself, allowing for a lateral rear support. It thus adds 2 more support points ( by removing the 3 rd back stem ).
