This is a quick shoe made of lightweight magnesium (metal). I am selling it because I no longer need it, as I have sold the equipment it was compatible with. Although it is new and unused, I have opened the package once to check the product. There are some scratches on the packaging due to storage. Some price negotiation is possible. Please feel free to contact me. https://www.velbon.com/products/detail/1101200152-00-00-00
