Kinashi Soul The Live Cap This cap was included as a souvenir with tickets to the Kinashi Soul The Live concert held at Zepp DiverCity on February 7, 2025. It is not for sale and is a rare item. KSTL likely stands for KINASHI SOUL THE LIVE. The quality of the product is very good, and I wanted to use it, but it didn't suit me... I would like to pass it on to someone who will cherish it. This item has been stored by an individual, so I am looking forward to purchases from those who don't mind.
