I think this is the last time I want to discuss this topic, at least with you.
1/ Your coming here and saying that the things my friends and I personally harvested, removing the non-oil wood, cutting, and testing it by smell multiple times to ensure that it's fake or not kinam, I don't care much about because your experience is limited to samples you’ve observed, read about, or through Japan or other third countries. It doesn't directly relate to us, and when you don’t understand it, using what you know to generalize all kinam samples from VietNam.
2/ Whether it is oil-rich or hollow will depend on the location where the kinam is formed. The area you circled is the part exposed to the air, where decay occurs strongly; at that point, it will decompose naturally instead of solidifying like kinam formed from the core of the tree
3/ We are all scent enthusiasts, and I hope you understand that before discussing anything, experiencing the scent is the most important thing. That’s why I rely on my perceptions and experiences to identify non-natural samples, many many times. I do not judge any of your items based on photos until I experience them in person, and I hope you do the same; this is the minimum respect.
4/ What kills us is not what we know, but what we think we know.
