I was looking to spruce up my concrete balcony.  I decided to take a chance with these tiles rather than get a boring patio rug (that wouldn't fully cover the balcony anyway. I decided to only get 2 just in case I didn't like it and would need to send back.  I ordered these on a Monday and received them on Tuesday (standard shipping).  After I am so excited to finish my balcony.  I am ordering 2 more boxes too complete!
