Primst 78inch/6.5FT Self Adhesive Edging Trim Srtip for Carpet Floor Mats, Suitable for PVC Edge Threshold Transition with Height Less Than 3/5 mm (5mm,Black)

The item comes on a roll which is usual for an item of its length. However, due to it being rolled, it kinks and is rippled along the thinner edge which looks dreadful when put down. Had to rip it up and throw away. Waste of money.
