A pair of Antique Chinese Kraak Blue & White Octagonal teacups & Saucers with double circle Reishi mark Qing Guangxu 1871-1908 and of the period.
It is much more difficult to make an octagonal shape for both the cup and saucer, as the corners are quite fragile after passing through hundreds of years.
But still such a elegant utensil for drinking both the oriental tea or British tea.
