This is a putting practice tool for indoor use. I used it indoors for about six months. The texture of the mat's turf is very similar to a real green, which was great for practice. The mat size is a large size, 367cm x 67cm. Some dust is attached. This is a used item, so please refrain from purchasing if you are sensitive to such things. Please check the photos for the condition. The outer box and mat storage bag are not included.
