Sekisui Chemical floor tiles, 4 pieces. I purchased these for use on my balcony and laid them down, but I bought extra, so I have 4 tiles left over. I will give them away to someone who needs them. * As a bonus, I will include two half-cut pieces. These were cut in half by me using a cutter. * See photo 3. The size is 30cm x 30cm. The color is gray. The surface has a plain tile pattern. They are unused and in good condition.
