This is one of the less common forms of Japanese cloisonne. We see tons of vases, but very few tea jars. The small jar is 4" high. The diameter of the top is about 1-3/4". I date this jar c. 1870.
This 19th C jar is in very good condition. No dents, but there is pitting to the enamel. Also, the enamel within some of the cloisonnes show wear. See what I mean when you examine the sixth photo.
This piece is a consignment. I will take your reasonable offer to the owner.
