Non-slip ramp to support dog care and health. I also think it can be used for ramps for bicycles, etc. I bought it for my dog, but he was scared and didn't use it, so it's almost new. Product Description Supports the ascent and descent of large dogs and elderly dogs, etc. ● Supports pets when going up and down in places with height differences, such as cars and entrances. ● Can also be used when loading bicycles and small motorcycles onto vehicles. ● Can be folded and stored compactly when not in use. With a stopper to prevent the main body from opening, for peace of mind. ● The surface has irregularities and is non-slip. Please see the image for the size. Will be sent in simple packaging.
