Our next-door neighbour but one found these things on the ground up the side of his house.
He doesn't know what they are, our next-door neighbour doesn't know what they are, and neither do I.
I asked him to take a picture, which he did (as you can see). I also asked him to include something for scale, bit I must admit I wasn't expecting an egg, a random mushroom and a digestive biscuit.
Being a bit of a card he did suggest something else, but after a brief discussion we decided it wasn't really appropriate. And anyway that would have needed a scale of its own, for obvious reasons.
If it helps, these things are double sided - the faces you can't see in the picture are the same as those you can. They are quite heavy - much more so than a small doormat, for instance.
We don't know if these mysterious items come in fours or you get them one at a time - you can put them on (or get them off) the metal loop by twisting it to open it up.
There is no maker's name.
Whaddya reckon?
P.S. If you think you know but aren't sure, by all means guess, but the guess has to be backed up with a photo or a link to something, else we won't believe you.
