I’ve just been through a painful patch of wound dressing and using awkward bandages, which is why I know that an improvement in design is needed. Although meant to be used as a Pain Relief Patch (for muscle pains), The Rolling Patch concept can be extended for all kind of bandages and First Aid dressing concepts. You can alter the length of the patch and trim to the requisite length, avoiding wastage and promoting easy application. Super!
