Kids hurt their fingers a lot. You can make an okay bandage with Kling wrap (see Vet Wrap), but if the injury is on a fingertip (a common spot) the cylinder shape you get from rolling doesn’t do as nice a job of protecting or of providing gentle pressure. You can fold over the end, but it gets bulky and inelegant for everyday activities. Tube Gauze is a quick, easy, elegant way to make a stocking cap for your finger or toe. The applicator (sold separately, but you can do without it) is a metal cage that holds the tube of the gauze open. You slide the applicator (or just the gauze) over a finger, lift it up, twist once, and then slide it back down. You can repeat several times to get the thickness of bandage you want. It gives a smooth, flat, elegant bandage — and it’s kinda fun to do. A hit with kids.
