Thank you, grassy.A key ring with a price tag stuck to it?
Thank you, heypresto.In BE we might call it a 'key fob' (with a price tag stuck to it).
Thank you, Andygc and PaulQ.Could you tell us what its purpose is?
It's a four-leafed clover. Therefore it is a lucky charm. You can see the four leaves and the stalk. There is also a lanyard and a ring. You wear it on a charm bracelet.No, I meant "How does one wear it?"/"How on earth are people supposed to wear it?"
