Thank you for viewing. I purchased many of these for guests. They have been used a few times or are unused. Due to moving and decluttering, I am selling some of them to those who need them and understand that they are used items. The set of 6 does not have a box and the manufacturer is unknown. Looking at the back, they may be Arita-yaki ware, but I am not an expert, so I am not sure. It looks like "Arita Seizan Gama?" is printed on them. The manufacturer of the bonus set of 2 is also unknown. I will pack them myself, but I will take care to prevent breakage.
