These are artificial turf tiles, each measuring 30cm x 30cm. They are being sold as a set of 6, but 2 of them are a different type, so it's not possible to connect all 6 (see image 3). They can be used in gardens, balconies, and as interior decoration, as well as a baby gate for babies in the crawling stage! We used them as a baby gate in our home. The prickly plastic on the back was especially effective, and we were able to use them until our child could walk. There are no functional issues, but there are scratches overall, as shown in image 9. I have cleaned them at home, but due to the structure, there is a possibility of pet hair and dust adhering to them. Please be aware of this. Instant purchase is OK.
