Color: Gray Mix. Appears gray, black, and light blue are also mixed in. The third photo is a close-up image. Size: 50cm x 50cm Thickness: 6mm Quantity: 16 sheets Weight: Approximately 24kg Bulk purchases are not available. These were laid in an office, but were removed without anyone moving in. The surface is almost new, but the back has some dirt from being laid down once and from the removal work. Due to the packaging size, I am selling them in sets of 16 sheets, but there are many more in stock. Please purchase the number of sheets you need. If you have any questions, please ask in the comments section. Packaging will be bubble wrap only. The carpet will be placed directly inside, so please be careful not to cut the carpet when opening. Thank you.
