Japanese ceramic handmade bowl with signature unused

This is a handmade bowl from Japan. It is beautiful ceramic light blue and with dark blue stripes. It is signed with Japanese characters. It has a unique dark line around interior. It is 6 in wide and three and a half inches tall. This bowl is more appropriate for decor rather than eating. It is so beautiful it's a waste to put food in it. But you can. The bowl is unused.
