Thank you for viewing. This item is almost new, having only been opened and tested once. I am selling it because it didn't work as I had intended. 【NDP-600E】Straight ◆Product size (approx.): Width 60 x Depth 27 x Height 10cm ◆Step: 10cm ◆Load capacity: Less than 10t ◆Material: Polypropylene ◆Compatible product: NDP-270CE ◆Country of origin: Japan 【NDP-270CE】Corner ●Product size (approx.): Width 27 x Depth 27 x Height 10cm ●Step: 10cm ●Load capacity: Less than 10t ●Material: Polypropylene ●Compatible product: NDP600E・900EPC Although the strength of the plastic seems less than that of rubber, I think it will be fine for things like hand trucks and bicycles. It has a decent weight, so I didn't notice much wobbling.
