This is a fashion mask sold at GU. It's a free-size, checkered pattern, and comes with one mask. It has an adjuster. It's unopened, but has been stored at home, so please be aware of this before purchasing. 【Regarding Shipping】 It will be shipped via Yu-packet Post Mini, but because it barely fits in the dedicated envelope, the top of the backing card will be folded. Please also be aware of this.
