OVERKILL, a sneaker shop in Berlin, Germany, officially collaborated with NIKE on this doormat. The catchphrase "KISS MY AIRS" was used and became a hot topic starting from AIR MAX DAY in 2017. This mat also features the print. The print is made of a paint-like material that doesn't easily come off. The mat itself is also made of a stiff, scrub-brush-like material. I think it can be used outdoors. I have never used it since I bought it. SIZE: 60cm x 40cm x 17mm It will be shipped folded.
