These worked perfectly for my Ikea shelves. The black color matches my shelves. These slipped on quickly and easily, lining the shelves up squarely. They look very nice! Gives it a block look at the top, looking like trim.Holds the shelves together and keeps them in place. They look even better than I thought they would! Easy to use and do the job as expected!
