Oil from the seeds of Camellia japonica is the traditional Japanese choice for protecting tools from rust: use it when cleaning, and as a regular protective coating. Leaves a lovely deep, non-oily finish, and it's odourless and tastless (handy for kitchen knives.)
If you're a sumo wrestler, oil your hair with it.
100ml- will last for years unless you drink the stuff ( but don't, it's mixed with paraffin).
We no longer send this to customers in the USA. Your FDA are untrusting of it. Sorry.
