Usually, having a big putting green at home requires a bulky, heavy and semi-permanent installation with all the associated headaches - until now! Expand-a-Green™ is huge, over 3 feet wide by 8 feet long, but the exclusive interlocking panels give you a modular green that assembles and breaks down in just seconds -and you can make it as big and shapely as your imagination allows with the use of expansion kits (sold separately). Fill up your game room, patio, or even your driveway with multiple expansion kits! Includes two flags and cups, and multiple pin locations allow you to practice a variety of putts. You can position the cup knock-outs underneath for varying breaks. Putts roll very true at a country club speed. Expand-a-Green™ is weatherproof and very durable, so you can set it up in a convenient place outdoors and leave it there as long as you'd like. Breaks down in minutes for easy storage. You no longer have to run to the club to practice like the pros, now you can do it at home - with your own Expand-a-Green™.
