The color, grain, and stripes closely resemble modern driftwood. This product contains non-silicified (not changed to silicic acid) black areas, and the contrast with the light brown color becomes more prominent when wet. It has been washed in fresh water, but if used in a place where plants or living things reside, it is recommended to wash it again just in case. ■■Please read the notes in the profile section■■ #Affordable Mineral Fossils
