Unopened souvenir of "glowing stones" that was popular a long time ago. This item is over 30 years old. If I remember correctly, I bought it on a school trip when I was a child. It contains six yellow stones (actual material unknown; appears to be an artificial material like plastic rather than a stone) with the property of glowing in the dark, housed in a small basket. It was completely forgotten and stored in a closet. The property still remains, and it faintly glows in the dark (please check the photos). This is a rather old item that was found by chance, so I believe it is a rare item now. Since it is unopened, I think the condition is quite good for a 30-year-old item. However, it has been stored by a private individual, so please refrain from purchasing if you are looking for a perfect, pristine item. There are no smokers or pets in my home. When shipping, I will use protective materials and send it via Mercari convenient delivery (anonymous shipping). I welcome bulk purchases. I will offer a significant discount from the second item onwards, so please feel free to contact me. Price negotiations are also welcome.
