I received this from a staff member when I entered the Italian Pavilion at almost the last minute on the final day. It says "Valtellina" on it. The size is approximately 2.2 cm wide and 2 cm long. I checked on Mercari, and nothing like it came up except for my own listing, so I'm wondering if it's super rare... What do you think? I will also be listing the ones my family received. If you know the value, please consider adding it to your collection. I will ship it via anonymous delivery. Thank you.
