Titleist PRO V1 YELLOW 1.5 dozen (18 balls) - Brand new, unused. Although the year is 2021, they have been stored in a dark place in my room, where the temperature and humidity are constant throughout the year, so I believe they are in very good condition even among the brand new, unused items. They still have the same smell as the balls when I first bought them. One dozen is completely unused, and the numbers are (1, 2, 3, 4). The remaining 6 balls are unused, leftover from when I used half a dozen. These 6 balls have a clover mark as an owner's name. The breakdown of the numbers for the 6 balls with the clover mark is: #1 → 1 ball #2 → 1 ball #3 → 2 balls #4 → 2 balls Please note that the box of the 6 balls with the clover mark has a slight crush. No individual sales, no returns or exchanges. Please refrain from price negotiations.
