Handmade ball markers Set of two unique, spring-themed Japanese illustrations. Diameter: 22mm, Thickness: approx. 3mm Suitable size for ground golf, as 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 my handmade items using resin. The inside (base) is a steel plate, so it adheres well to magnets. 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 at the product list. These are handmade by an amateur, so there may be some imperfections, but please understand.
