Small moon shaped tea pot?

Hi folks, not at all sure what this is called or whether it is an Asian item.  Hoping someone will know something about this piece. Not in the best condition and I have altered the contrast a little plus the light as it was so sunny in the garden. This is now pretty much the real colours. A very dark brown glaze to the whole body with the green mixed glazed poured over this by the looks of it. It looks like it could be glazed inside too? The glaze certainly goes down as far as can be seen with eyes only. Any idea on age and country of origin would be much appreciated. Thank you.
