I find this object attractive, but extremely peculiar. The Vas Wood Diffuser, by Norwegian aromatherapy company Vörda, is like an inverted, turned wooden chalice made from Hinoki (a type of Cypress found in Japan).
Apparently you use it as a storage lid for a jar of essential oil, which you occasionally squirt into the shallow bowl at the top:
The wood absorbs the oil, and the scent reportedly hangs around for 8 hours or so.
I'm not part of this essential oils world so it all seems very strange to me, but I suppose people like their rituals.
I think if I hadn't found the link to buy one of these, I'd have assumed this was a design student project.
