These are great golf balls for the beginner or inexperiennced golfer. You can get 18 for around 8 dollars at walmart. These golf balls have a fluid meatal core which I would assume they are made like the older balata balls were but with a mix of zinc,neodymium and titanium. Feel wise to me they are about like the old Titleist HP2 tour. Its not the best ball but for the price I think its a pretty good deal.
