This is a set of 6 can badges for Nijisanji's Rou Koyanagi's 2023 birthday. I purchased them online and have stored them in a dark place. They are unopened. If sold individually, I am accepting offers starting from 2700 yen per badge. If you would like to purchase them together with other items I have listed, please let me know in the comments, and I will offer a small discount and ship them together. Instant purchase is OK. Price negotiation is OK.
