This is Park Bogum's official light stick, Forebon ver. 1. Includes box, strap, and instruction manual. Purchased about 6 years ago at a fan meeting in Seoul, and I think I used it about 10 times. The "BG." part is loose. Light-up function confirmed. Please purchase only if you understand that there is a feeling of use on the main body, strap, and box. Batteries are not included. Please check the photos for the other conditions. This item has considerable signs of use, so please purchase only if you have confirmed this.
