I purchased this at Sakagami House Cafe. The "Unchi" (Poop) series is a very popular product. Although it's unused, I've marked it as "Like New" because I've lost the instruction manual and the plastic wrap that covered the item. I would appreciate your understanding. I have confirmed that it powers on. Here's the product description: The first in the "Unchi" series! A rechargeable LED charm. It lights up in 7 colors! Attach it to a collar, leash, or bag for safe evening walks♪ (Includes a charging cord) [Lighting Patterns] ① All colors slowly changing continuously ② All colors quickly changing continuously ③ Manual color change [Color Patterns] Red, Green, Blue, Yellow, Light Blue, Violet, White (7 colors total) * Approximately 4 hours of use on a full charge (charging time is about 1 hour). * The LED will light up red while charging. It will turn off when charging is complete.
