Thank you for viewing my products♡ This is a flat lesson bag, an essential item for preparing for kindergarten and elementary school. Also selling bags with gussets~ Suitable for school, lessons, etc... I've chosen fabrics that can be used not only by kindergarteners and lower elementary school students, but also by upper elementary school students. It also has a pocket inside for small items. Fabric: Star pattern...80% cotton, 20% linen Denim...100% cotton Size: Approximately 40cm x 30.5cm, flat (may have an error of about 1cm) Shipping will be in a clear bag and a simple envelope. It will be folded for shipping, so there may be creases in the fabric. Thank you for your understanding. I am also selling on other sites, so if purchased on the same day, the first person to purchase will be given priority. Thank you for your understanding. Please feel free to ask if you have any questions. This is a handmade item, so please refrain from purchasing if you are sensitive to such things.
