These lichen green ceramic buttons are simple, robust and have a lovely feel to them. They measure 0.7 inches across, have been high fired and I've ensured they are glazed front and back (see photo 3) making them non porous. The glaze is matte, slightly darker here and there around the edges, some with a slight crystallisation. I am so very happy with these buttons.
