I had this exact same thing
stiff part protrudes out. The part that protrudes outward is colored black and is very stiff / hard. After pulling it out the inner portion is colored white and is very soft. It is about 1cm in length. There isn't really a scent.
It grew back after a few years , apparently it's ok to pull outView Thread
