Is this a sin?

So I recently as a gift from my cousin gave me a pendant/chain Of The Grim Reaper/Holy Death. It looks cool to me. I was wondering if its a sin to wear it not Because I obviously believe in The Death reaper or whatever But I just think it seems cool. Would it be a sin to wear it even with no demonic or evil intention?. It just shows a Grim Reaper like figure With a scythe. I want to wear it Like i said simply because I think it looks cool. Male 19 Btw.
