I received this in October at a Chopin concert held at the Poland Pavilion, a difficult-to-get-into attraction at the Kansai Expo. It's a rare item, as it was a concert limited to 50 groups per session, and I was lucky enough to win a same-day reservation in the fiercely competitive lottery. It appears to be an official item from the Chopin Society, related to the 19th International Chopin Piano Competition in 2025. I would be happy if someone who appreciates its value would take it.
