Handmade Ball Markers Set of two ball markers featuring a cute calico cat illustration. Size: 22mm diameter, approximately 3mm thick. Suitable for ground golf, adhering to the size recommended by the association. This type can be attached to a magnet for portability. Magnets are not included, so please use a base with a magnet, such as a clip. These are handmade by me using resin. The inside is steel, and the back is finished with stainless steel foil. They sparkle in the sunlight, making them easy to find, and are perfect for various types of golf. How about a small gift for your golfing family and friends? I also have 25mm markers and other handmade markers with different designs for sale, so please take a look. These are handmade by an amateur, so they may not be perfect, but please understand.
