Friend Won’t Return Antique Item

In 2021 I rehomed my snake to a former friend. At the time I was using an antique Japanese geisha doll case as the snake cage and let them take it under a verbal agreement that they would buy a new cage and return my doll case.

Fast forward to now, I left the country unexpectedly for a couple years & came back. This person reached out to me to hang out but I told them I just wanted my doll case back. They have now blocked me on Instagram. After doing some digging on their tiktok I see they have a new snake cage and my antique is nowhere to be seen.

I really don’t have any proof of this other than some texts from a few months ago of me asking them to return my case. Do I have any legal options to take against them? Can I report this as theft?
