Part of the 3M Sports Games line, the wrap-around box is a double sided board with 18 holes from various golf courses. First you determine wind speed and direction. Then pick your club, place the range-finder on the board and roll for your shot. First you roll on the distance table then on the direction table to determin where your shot landed. Make a mark on the laminated, eraseable board. Do this until you reach the green then roll on the putt table.
