Thank you for viewing! This is a small insulated/refrigerated drawstring bag made with simple checkered fabric. It's perfect for things like frozen jelly or chocolate. The lining uses an insulated/refrigerated sheet, so you can use it year-round. Outer fabric: Oxford Lining: 4-layer aluminum insulation/refrigeration sheet *The refrigeration sheet is dry-cleanable and washable (gentle wash). We recommend using a net when washing, and hand washing for long-term use. *Heat resistance is -20°C to 80°C. *The aluminum foil has a top coating to prevent peeling, so do not tumble dry. *After washing, if you iron, gently pull out only the refrigeration sheet part and iron only the outer fabric. *Please be sure to check the size. Size (flat): Height: Approximately 11cm Width (opening): Approximately 19cm, Width (bottom): Approximately 11cm Gusset: Approximately 8cm *Please allow for some error. *Please note that the color may appear different depending on your device. *This is a handmade item. There may be some fraying or distortion, but each one is made with care. Thank you for your understanding. *We have a pet (dog) at home. We take the utmost care to prevent pet hair from sticking, but there is a rare possibility of it occurring. Please be aware of this if you have animal allergies or are concerned about pet hair. *Prices may vary due to rising raw material costs, even for the same materials and shapes.
