It's not a mini golf set, it's a mini golf course! Build it differently every time, and play in the dark with light-up balls. Set up each of the 5 holes with one of the obstacles: ramp, zig-zag, tunnel, or the moving windmill, to maximize fun for family and friends. Comes with a 72" x 90" green felt putting mat, 2 putters, 5 tee mats, 33 tees, 4 blacklights, 5 obstacles, and 2 LED glow-in-the-dark golf balls, all of which fit neatly into the storage carry bag. Includes 12 AAA batteries. For ages 4 yrs-adult, from B4 Adventure.
