The instruction sheet was rolled up inside this bolt of stringcloth wallcovering . As you can see, some of the ink came off and discolored the wallpaper . This is not uncommon. I had to throw away the first 10″ or so of paper (about 2 sq ft of paper). Other things can damage the ends of rolls , too, like tape , impressions / dents created by labels or packaging , edges banged up during shipping , and more. Another reminder to always purchase extra paper .
Some wallpapers are more delicate than others, and can be damaged during shipping. Some manufacturers have started using these cardboard caps to protect against getting banged up.
