These are souvenirs from when I worked at the Expo. The badge in the middle is unopened and not for sale. The badges on the neck strap for Myaku-Myaku are from the Portugal Pavilion, the Canada Pavilion, and I've forgotten the other one. There are a total of four badges. The Myaku-Myaku neck strap is also included. I only worked at the Expo, so I'm not very interested in these items. I'd like to sell them to Expo fans as souvenirs.
