Pencils made from Incense-cedar (a renewable resource) are a reddish brown inside with a smooth, fine grain and a visible seam. They also have that familiar cedar scent when sharpened!
Pencils made from tropical rainforest wood have a brownish color with little dark brown or red flecks. It is very hard to see the grain, and they have a slight scent
