This is a Bizen-yaki teacup. It's a reddish-brown color, like chestnut. I opened it for the photos, but it's unused. I received it as a gift, but I don't have a chance to use it, so I'm selling it. Below are the actual measurements. Please note that there may be some slight errors due to amateur measurements. Maximum width: Approximately 7.3cm Height: Approximately 7.0cm Mouth diameter: Approximately 6.7cm
