This is a nice kit, but I would have preferred uncut lengths equating the same material. I use a similar product in a much larger size that comes rolled in a plastic bag--a much better idea. Sometimes you need more--sometimes less. It's nice to cut off exactly what you need from a roll. While the case is nice, it is unnecessary for my needs and takes up much more space than a plastic bag. But because these are pre-cut, the case is necessary to keep the pieces organized. With that said, this is really good shrink with glue and you need a heat gun to set it.
