Thank you for viewing my products♡ This is a lunch 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. And considering the heavy loads children carry and the strain on their bodies, I made this bag as lightweight as possible, so I didn't use lining fabric. Fabric: Star pattern...80% cotton, 20% linen Size: Top width approx. 28cm x height 16.5cm x gusset 14.5cm (An 18cm x 11cm x 6cm lunch box fits well) (There may be an error of about 1cm) Shipping will be in a clear bag and a simple envelope. I am also selling on other sites, so if you purchase on the same day, the first person to purchase will be given priority. Thank you for your understanding. If you have any questions, please feel free to ask. Please refrain from purchasing if you are sensitive to handmade items.
