I purchased this at a souvenir shop called Kosho-do in Asakusa. It seems that the "Kosho-do" branding is exclusive to this shop, and it's said to appear in historical dramas like "Berabou" and the Touken Ranbu series. It's a great choice for souvenirs! It's new, as I haven't taken it out of the bag, but please refrain from purchasing if you have any concerns.
