Hoshino TN makes my bag smelly.... Any solution?

I finally got my hands on the limited edition Hoshino! 🥳
Bought it from Mercari, and the original owner apparently hadn't used it for a long time, so it arrived in almost new condition.

BUT there's one problem—it has a pretty weird smell. I've owned two other TNs before, and they never smelled like this. It's hard to describe, but it's kind of like lambskin... which it definitely shouldn't be?

I'm absolutely in love with the texture though. Does anyone know how to get rid of the smell?
