Wasnt expecting the little bag to put the Alignment tools in.Pleasantly surprised.I received this product quickly and in good shape via USPS. The product was exactly as expected. I use these to mark a line for putting. I don’t use the diagonal or perpendicular lines. The groove for the putting line on my part is a little narrower on one end than the other, so use a newer Sharpie if you want a nice solid mark in your ball from front to back.I have a ton of different ball liner tools, but this is my favorite because of the hinge, as opposed to the others that the ball fits into. I use it even for the balls that I just find on the course, keep a few different color mini sharpies in the bag (my color this year is red). I don't use the ball striking side, I find it too distracting, but YMMV.The price for 4 of these devices to mark golf balls was equal to what I paid at a golf store for just one. I almost did not believe it.So...if anyone reads this, maybe you’ve had sloppy ball markers before. This is the best I’ve ever had. Thin, sharp lines...and the spring clamp makes it very easy to use!I always play with a marked ball of my own design. This has so many options to mark a ball that makes it unique to me. I don't like playing with people that don't mark their ball. They can pull any old ball out of the woods and say it is theirs. I don't believe them.Changed my golfing life. get them use them trust them and it will rewrite your score card I am a confident putter and I make a lot of putts because of this product. It always seems the cheapest products make the biggest difference in the game. Get it. bought th e4 pack for my buddies they love it as well. PEACEPretty cheap and most are slightly chipped. Doesn't fit regular sharpies very well so be careful what markers you get for it. I do however like the lines. I used the cross side for putting and the arrows one for off the tee.
