This is a set of two golf markers featuring a family crest illustration (Ken Katabami). Diameter: 22mm, Thickness: approx. 3mm The size is suitable for ground golf, conforming to the recommended size by the association. These are the type that can be attached to a magnet for portability. Magnets are not built-in, so please use a base with a magnet, such as a clip. They shine brightly in the sunlight, making them easy to find and ideal for various types of golf. These are handmade items made with resin. The base inside is a steel plate, so it adheres well to magnets. The back is finished with stainless steel foil. Why not consider them as a small gift for your family or friends who play golf? I also have other markers with various illustrations in 22mm and 25mm sizes available, so please take a look. As these are handmade by an amateur, they may not be perfect, but please understand this point.
