Problem with size
The first time I ordered these I recieved 18"x 25'. The customer service easily managed the return. I was told a person in the werehouse would confirm the size on the reorder. The reorder came quickly but with the same size error. The boxes could not have been more clearly marked 18 inches. The lettering could be read at 150 feet. Either it wasnt verified or the person ignored the product description and will ship the wrong item indefinately.
