Great

After reading other reviews I bought more than I needed - and yes these are indeed smaller than expected (which (ignoring the paradox) I had expected).So.... How small I hear you ask? - well about 55mm in diameter - and based on rough measurements from various web pages - about the size of a professional pool ball (52.5) or a little smaller than a rounders ball (61) - both being smaller than a tennis ball (68))
