Permanently attaches on ALL shapes of golf grips no matter the size of the grip, as long as there is a small hole on the end of the clubs grip. Course threads on the 1/4 inch screw makes it virtually impossible to pull the picker out of the grip when pulling the golf ball out. (SOFT ENDED club grips MAY NOT hold or if the grip has a large hole on the end) Fits in EVERY Golf Bag!! Golf Pros who have been in the business for 25-30 years have said, "This is the golf ball best pick up tool they have ever seen since it not only picks up the golf ball, but also picks up the Flagstick and any extra clubs brought to the green besides the putter." The GraBall Picker Upper is a unique, well-made, patented golf ball retriever! The fingers do not collapse or fold up in hot weather. Cold or wet weather does not affect how well it works, reducing the need to bend over to a fraction of what is required with other golf ball retrievers. Furthermore, this product is sturdy and it will last so much longer than the traditional golf ball retrievers. Treat yourself to the best golf ball retriever by ordering one for your putter or even a 2nd or a 3rd one for your favorite greenside chippers to pickup your putter when taking two or three clubs to the green!!
