Looking for linseed oil in BXL (Brussels)

Hello everyone,

i am looking for linseed oil to oil my two new wooden flutes.
I have been told it protects the wood from the humidity due to blowing in it so i need some but i have absolutely no clue where to buy this.

Anyone's got a clue ?
It would help me a lot, now i don't dare playing with the flutes anymore, which is good for neighbour but not for me :)

Kind regards,

Yannick
