We have steps on our indoor stairs to reduce wear on the stair carpet itself. The steps were difficult to hold in place and we have used various brands of double sided carpet tape with moderate success. Of course, only time will tell how good Mr. Pen is, but based on first impressions we're optimistic that we've finally found a product to work with. The tape was easy to cut (although the adhesive is so strong I had to scrape the goo off the scissors several times during the process), easy to apply, easy to peel from the backing and easy to hold in place.
