This product is a set of eight demitasse cups and saucers, made in China during the Qianlong period(if stamp is true)of the Famille Rose style. The set features a pink, green, gold color and is regionally specific to China. There are 2 sets with the triangle yt mark and the other six sets have the stamp that I searched as Qianlong. There are no chips just normal paint wear and gold missing.
Please let me know if you have questions.
