Thank you for viewing! This is a square cup measuring 7.9cm by 7.9cm, and 4.7cm in height. There is no outer box or accessories. I'm not sure of the material, but it feels light, so I think it's plastic. It's not ceramic. I received it when attending a wedding and only used it on that day. I hope it can be useful to someone, such as those who enjoy sake or those who are looking for table decorations for celebratory occasions. Thank you! :)
