Crepe bandages can be used for a range of reasons, including to wrap up a sprain, for general purpose bandaging and, perhaps most importantly, as a pressure immobilisation bandage, which is the recommended treatment for snake-bites and bites from a few other venomous creatures.
They are an essential addition to any first-aid kit. This 5-pack contains 2 10cm crepes and 3 7.5cm crepe bandages.
