Hello
I have a clear ashtray that is square with an amoeba-like centre and half-spheres cut into all four sides. it is beveled everywhere except the circular parts. I have an idea it might be Czech as it's very similar to a blue ashtray I have by Exbor, but this one doesn't have an name on it.
It is 9.5cm across and just over 4cm high.
Many thanks
Santa
