marna Door Stopper Locks with a step. Release the door with a "pop" | Smoothly usable door stopper Locking is instant, just step on the pedal. Unlocking is also instant. Just push the door outward with a "pop" without touching the stopper directly. I have been using it for about a year, so the lower right area of the first image is slightly faded. There is no problem with use, but please refrain from purchasing if you are concerned. I am selling it because it is no longer needed after moving from a rental property to a detached house. *Instruction manual and box are not included. I will consider a small discount if you purchase immediately, so feel free to comment. - Brand: marna - Color: Black - Type: Door Stopper
