I work right near their NYC store, and imo they have pretty good stuff. They boast about their process (ala their name), and the duplicates i've gotten from there vs other providers seem to be good quality.
Their Rosewood is much "fuller" than what I've gotten elsewhere.
They have a great Japanese Mint, that seems to be pretty unique.
They are fairly pricey, though.
Fair warning… i'm definitely on the novice end of the scale on these forums. So hopefully others will weigh in too.
