Rough Palygorskite.

This curious mineral that comes from the alteration of magnesium silicates in soils and sediments, is called "Mountain leather" or "cardboard stone" due to its flexibility, it is a mineral that can be bent and does not break. It is usually found in amorphous sheets.

The mineral includes a label with the name, origin and is attached to a 4 cm square cardboard box.

*The price is per unit (a single cardboard box of the four shown in the image)

Since the minerals are natural, you will receive a piece similar to the one in the photograph. The samples come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the mineral. The size is approximate.
