I purchased this product for my son's room. He had previously been given 3 other rolls as a gift from an aunt. So I know one of these rolls should measure 15ft (5 yards-it also says so on the packaging). I needed to purchase one more to complete his room. I just finished putting it up on the wall and found that this roll had been cut short by about 9 feet! It became even more obvious that this was the case when I got to the end and noticed that it didn't end in a nice smooth straight line, like it would have, had it not been tampered with and cut short! I am very unhappy with the seller who I purchased this through via Amazon! I will be contacting the seller and demanding a replacement or a full refund. Other than the 'shady' practices of this seller the wall paper border itself is very cute (perfect for any spiderman devotee's bedroom) and it's fairly easy to apply.
