These are glass shelves that I have used in my shop for many years. The size is approximately 560 x 305 x 5mm (please allow for an error of about 1mm). This is a set of 3 shelves. Since they were used for display in the shop, there are inevitably some surface scratches and scratches on the corners. Thank you for your understanding. I still have stock of glass shelves of this size, so I plan to list more. As these are glass shelves, I will take extra care in packaging and handle them with more care than usual.
