No comments necessary, immediate purchase is possible. Rilakkuma design mosquito repellent bracelet. One each of yellow and pink. I am listing these as I purchased them but did not use them. These are mosquito repellent rings that are one-size-fits-all for adults and children. The effect lasts for about 1 month, so how about them for the summer vacation period? The design is cute, so they can be used by a wide range of people, from children to women. They have been stored at home, so please only purchase if you understand this.
