Last year, my wife and I went to what was apparently the 2nd Dubai World Championship (Race to Dubai) which was held at Jumeirah Golf Estates. I was able to purchase the five different ball markers shown above: those in the first two rows had gold- and silver-rimmed varieties; the last one came with a golf glove. I also purchased a leather-bound, magnetic money clip which has what appears to be a larger ball marker that is permanently affixed. (I didn't have the heart to destroy the leather casing to see if it does contain a ball marker.)
I have some free General Admission tickets to the championship this year, and I hope to go either on 9 or 10 December. I'll be disappointed if there are no new ball marker designs.
