This is a limited-edition towel from the "Hozuki's Coolheadedness" event held in Noboribetsu Onsen. It features illustrations by the original author, Natsumi Eguchi-sensei, with various characters depicted in colorful detail. I believe it's rare to find this item brand new and unopened. For those looking for it! Ms. Eguchi is also the author of the currently popular "Dekin no Mogura." Goods with illustrations from the original work are rare, so I would be happy to pass this on to fans.
