These are petrified wood that has been carved and polished into the shape of a horn. They are very smooth and cool to touch as you would expect petrified wood to be. Each one is different and I only have 3. They are simply not something you can buy just anywhere they are for collectors and curators of things natural and earthly.
Size- The largest is 30cm long and the other 2 are 27 cms long.
Composition- Wood 100%
Care- just with a damp cloth, do not drop and will certainly fracture.
