Having been an onsite bricklayer for 30 odd years I regularly, quite literally wore out my fingers drawing blood on the abrasive bricks. Micropore was a life saver enabling me to continue just topping it up as and when. At the end of the day when removed my digits were not too soft and peppy either. I always keep a roll in my van as well as my kit alongside my sudocrem (magic cream ! )For years I have been a firm believer in Micropore. It is so porous that one can leave it on for a long time. It gets dirty but with some use of an antiseptic it can be kept on until it wears off or the wound is no more a problem.
