Thank you for viewing. This is a Japanese paper tatami mat made by Daiken. I received it from a tatami shop I know. - Color: Silver white - Design: Diamond pattern - Length: Approximately 174cm - Width: Approximately 86cm - Thickness: Approximately 3cm There are no problems, but please note that there is writing on the back of the tatami mat in the 11th image. I have multiple mats available, so please feel free to inquire. Thank you.
