This is truly a beauty to behold! This is a rustic and substantial shelf unit that is made from a variety of tropical hardwood species. From what my wood expert and I could tell, there is teak, acacia, rosewood, and possibly padauk in the mix as well. The wagon wheels on each side and the support legs are all made from solid teak, the shelves themselves are a mix of rosewood and teak with acacia shelf supports. This piece is very special and made from wood that is getting harder and harder to obtain.
