I purchased this from Cainz in February of this year and used the electric carpet/mat for only 30 minutes. I have disposed of the instructions. Electric Carpet: 162cm x 166cm, for 2 tatami mats Mat: 180cm x 182cm *Please note that there may be a margin of error of 1-3cm due to manual measurements. Although it's in near-new condition, I will conservatively rate it as having no scratches or stains. Please refrain from purchasing if you are overly concerned about minor details. I plan to fold it up compactly for shipping. Thank you very much.
