Thank you for viewing. This is a listing for a level marker. More precisely, it's a level that can be used with a marker (#^.^#) It doesn't have a base or magnet, so please carry it in your pocket, etc., and use it. The white color makes it highly visible from a distance, and the fact that the reference inclination degrees are indicated on the scale is the selling point of this product (^_^)v The bubble moves according to the slope when you place the marker, so you can see the slope immediately. I also have many other golf goods for sale. If you leave a comment, I can offer a discount and list them as a set, so I hope you'll take a look (^_^*) 〓Product List〓 #kuu-shop Golf golf putter putting 1 putt stroke competition golf ball
