MR. GADGETS button ball markers
http://www.mrgadgets.ca

One of my most favorite golf accessories is the button golf ball marker that fits over a button on my golf shirts. Made in Canada and economically priced. Most golf tournaments at better golf courses required a polo shirt. Those shirts have buttons and this product is ideal. No more fumbling in pockets trying to find a ball marker amongst the tees and divot tools. Check it our and there are even more products from Mr. Gadgets.
