Handmade ball marker set: includes two finger-pointing illustration markers and one black silicone clip with a magnet. Markers: 25mm diameter, approximately 3mm thick, adheres to magnets (no magnet included). Silicone clip: Contains strong magnets on both sides. Use with steel or magnetic markers. Suitable for various marker sizes. Can be clipped onto the brim of a hat, pocket, cuff, etc. ◎ If you prefer, I can substitute the markers with any other markers I have listed. Please inquire in the "Questions" section before purchasing. The decorative part of the markers is handmade by me using resin. The base uses pre-made steel plates for golf markers. They sparkle in the sunlight, making them easy to find, and are perfect for various golf games. The clip is not handmade, but a commercially available product. I also have 22mm markers and other handmade markers with different designs listed, so please take a look at my product list. These are handmade items, so they may not be perfect.
