To ask what this clip is called

[ClarasZoo]

And where can I buy them? It was on a packet of socks and had a hanger style hook on which I snapped off. I love popping the clip on and off!!

I’m not sure OP but this is the cutest post I’ve seen

I know it's not really AIBU - sorry - but I really find it helps with stress to pop them on and off!
