Thank you for viewing my products! This is a cup bag, an essential item for preparing for kindergarten or elementary school. I've chosen fabrics that can be used not only by kindergarteners and lower elementary school students, but also by older elementary school students. It can also be used as a drawstring bag for small items. And considering the weight of the luggage and the burden on the body, I made this without using lining fabric to make it as lightweight as possible. Fabric: Star pattern...80% cotton, 20% linen Size: Approximately 21cm x approximately 17.5cm, no gusset (There may be an error of about 1cm) Shipping will be in a transparent bag and a simple envelope. I am also selling on other sites, so if you purchase on the same day, the person who purchased first will be given priority, so please understand. If you have any questions, please feel free to ask. Please refrain from purchasing if you are sensitive to handmade items.
