In my opinion, if you feel comfortable in them, and you aren’t going to buy anymore in the future, then keep them and still use them everyday, if you don’t feel comfortable wearing or using them after a while then I think you should sell them or give them to someone you know or a second hand store/charity shop, this way it can stop someone buying a new leather item another animal has died for and will possibly save an animals life. Hope this helps 🙂
