◆Ebonite (Japan)
There's a substantial quality difference between Japanese vs Chinese / Indian ebonite.
the biggest issues we noticed with chinese / Indian ebonite is as follows:
1. lots of contaminants
2. lots of pits and micro-cracks
3. more nasty smell

Japanese high quality ebonite material does have the above problems as well.
However, the frequency of the problems we experienced is literally much, much less.
(we have experience with Indian / Chinese Ebonite as well, although they are not used anymore)
