Lusterware teacup and saucer made in Japan blue and orange vintage cup

This listing is for a beautiful vintage lusterware teacup and saucer that was made in Shofu Japan in the 50s. The cup and saucer are a lovely pale shade of blue on the inside and orange on the outside. The iridescence of this set is beautiful.
The cup and saucer are in decent condition- in the last 2 photos you can see a small chip on the rim of the saucer. This chip is not visible when upright.
The saucer measures 5 1/2 inches in diameter and the cup measure 4 inches in diameter.
