Seem to be low quality specimens. Sampled several from the same bag, some of which were resinless with little aroma beyond wood. Also tried select Cambodi--similar though slightly less resinous, with no meaningful difference in aroma. I guess that explains the 20%off sale. Years ago, I purchased oud incense sticks (different seller) made from "upcycled" (previously distilled) oud and this is the smell I am reminded of. The scent is also thin and dissipates quickly. Disappointing. I will not be back.
