51 x 80 cm, approximately 1.5cm thick. A sturdy entrance mat. Used for only 2-3 months, but I ended up not using it, so I'm putting it up for sale. It's clean with no noticeable stains, but it's not unused, so please understand that it's a used item and may have minor pilling due to the material. I will fold it lightly to make it compact for shipping. I think it can be shipped in a slightly larger box if you use Eco-Mercari delivery.
