This is an unused, unopened promotional pin badge for the 28th single, "Gakuen Tengoku," released in November, around this time in 1989. It's quite rare. Although it is unopened and unused, it is a very old pin badge. There is definitely some age-related deterioration. In fact, as you can see in the image, the back side is a little blackened in places. Please consider this with the understanding that it is not something recently made. For safety's sake, please consider it as a "used item." Please consider this only if you understand the above. Shipping will be via Yu-packet Post Mini. No claims and no returns are accepted. Regarding the transaction, I am not in a rush, but I hope for a normal, prompt, and smooth transaction. Finally, if you have any questions, please do not hesitate to ask. #valuable #old #vintage #antique #collector #collection #treasure #value #set
