This is a karuta set created by Calbee, featuring 45 winning entries from their "[My Can't Stop, Won't Stop] Campaign," selected from 31,678 submissions. Illustrator Morito Toyonaga created the illustrations for the picture cards. It's a non-sale item with a limited quantity, so the fact that we have one means... my son must have made a pretty expensive purchase... I guess (((laughs I wanted to list it as new and unopened, so I'm not entirely sure what's inside. You can probably see some of it on the official website, so please check there. https://www.calbee.co.jp/yametoma-karuta/ Thank you for looking.
