This is a rubber band that secures items using Velcro. The size is approximately 40cm x 2.5cm (width) and stretches 1.5 times its original length. Available colors are gray, navy blue, and army green. While I've only tested it and haven't actually used it, there is some slight fuzzing from the testing. The length can be adjusted by changing the position of the Velcro closure. Also, by connecting two bands, you can use it for larger items (do not use for securing heavy objects). Suitable for lunch boxes, yoga mats, outdoor activities, etc. Lunch belt
