Do you have children that just love to slam the doors. I have found a solution. I will only cost you 1 dollar. Buy a fun-noodle.
Cut the noodle any size, mine is about 10 inches, It probably doesn’t need to be that long.
Then slice the noodle up one side. ( as shown in the picture)
Then spread it open and place it on your door.You can put on top of your door or on the side like mine, eith way will do the trick.
Just that easy. It will save you from having smashed fingers
