This is a pair of grass skis from the brand AUSUS. I received them as a gift and don't know the details, but I have measured the size and included it in the images. I am also selling grass skis from the manufacturer rollka in a separate listing. Please take a look if you'd like. The main unit will be wrapped generously in large bubble wrap and shipped without a cardboard box. I cannot answer technical questions, so thank you for your understanding.
