Stunning Little Blue and White Porcelain Bud Vase

To my eye, this little porcelain bud vase is just about a perfect object, only to be made better filled with a few violets, or hellebore, or lily of the valley. Unsigned, I don't know who made it, but it feels very Japanese and very zen. Very thin walled porcelain, with an eggshell sort of texture and very finely incised and painted china blue lines.

3 3/8"  widest, 2 1/4" tall and in great condition.  A bit of very minor staining around the opening, which I am only noticing in detail photos.
