Wonderfully kitsch plastic rings - probably for children as they only fit my little finger.
Although the backs are open so will also fit, very snugly, on your ring finger.
The ones I have described as Big are 2cm tall and have wider sides, the Small are 1.7cm tall
The pictures are the same size.
They have fantastic MOVING pictures of a footballer just about to score a goal or 2 boxers..
You move the picture backwards and forwards and the figures move...its called lenticular, apparently.
And is very difficult to photograph !
The pictures are glued on - I've repaired any that have come loose but they may fall out in the post - really easy to just glue back in.
The smaller ones have HONG KONG stamped on the back.
