The inside is lined with vinyl, so you can put wet items in it, making it very convenient when you go out. It's also useful for storing items that you're worried might leak. Size: Approximately 32 x 26 cm This item is from "Nichiyokan," a select shop located on the grounds of the Manpei Hotel in Karuizawa, which carries a wide variety of excellent works by Japanese artists. My family is a big fan and always buys various items there. Since they are all one-of-a-kind items, you won't find anyone else with the same thing. It's a good quality item, so I hope someone who will use it will take it. Although it is a new, unused item, it has been stored at home, so please consider this before purchasing.
