This is an internal divider designed specifically for the Ikea ORDNING utensil holder. It provides structure and organizes your tools efficiently. At the top it has a lip that grips the edge and there is a 'stake' at the bottom that fits into the central hole to prevent any movement. This dividing line is made for the smaller Order holder, which is 13 cm high. Some containers may be slightly larger, which may not provide a tight fit.
