For my birthday, I had a leather Golf Organiser bought me which I find very useful. It clips on to your belt or golf trolley. Inside you will find such things as a pencil, a divot tool, ball marker, scorecard and some wooden tees. Inside the elastic hoops keeps everything in place.
I particularly like the magnetic clip which holds the scorecard in place while I scribble my scores down.
I might buy one of these to give to a good friend of mine for when we have a game of golf together.
