Handmade ball markers Set of 2 with a smiley face design. 22mm in diameter, approximately 3mm thick. Suitable for the recommended size by the Ground Golf Association. This type can be attached to a magnet for portability. Magnets are not included, so please use a base such as a clip with a magnet. They sparkle in the sunlight, making them easy to find, and are perfect for various types of golf. These are my handmade items using resin. The inside is a steel plate, and the back is finished with stainless steel foil. How about a small gift for your family or friends who play golf? 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 there may be some imperfections, but please understand.
