Couple's Teacups ? Made by Matsunaga ? Raised floral design resembling braille ? Beautiful condition ? Saga inscription

These items come from my parents' home. They have been stored without being used, so I believe they are in good condition. These are teacups made by Matsunaga, featuring traditional sometsuke (blue and white) patterns. They are ceramic tableware. Blue plant motifs are depicted on a white background, with a small and simple shape. They can be widely used not only as soba choko for noodles but also as teacups for drinking tea, small bowls, or sake cups. The underside is stamped with Saga. There don't seem to be any major damages to mention, but we ask for your understanding that these are used items and have been stored at home. The sizes differ: one is approximately 5.8cm in diameter and 7.8cm in height, and the other is approximately 6.2cm in diameter and 8cm in height.
