Mask elastic cord White 4mm 10m x 2 rolls (20m total) Brand new, unopened. I haven't taken it out of the bag, so I haven't measured the exact length. The first photo is the actual product. The second and third photos are of the ones I opened for my own use. This is an elastic cord, so it may not be exactly 10m. It may be slightly shorter or longer. The store label says 10m x 2 rolls. Please refrain from purchasing if you are overly concerned about details. Thank you for your understanding.
