I keep finding small things disk shaped things in the sand. I imagine many of you will know what I am on about but they are hard to desribe. They are circular, about 4millimetres in diameter and 1-2 millimetre thick. They are a hard material and most of them are opaque though I think some have a stronger colouring. The edges have been smoothed off by the sea.
What are they?
