Thank you for viewing! I've made a mini drawstring bag and ice pack case using a cute cat pattern and a thermal insulation sheet. I think it can be used for rice balls, small drinks, or snacks. ◆ Thermal Insulation Drawstring Bag ★ Size: Approximately 13.5 cm in height (from the string down, approximately 11.5 cm) Approximately 21.5 cm at the top width, approximately 11.5 cm at the bottom width Approximately 10 cm in depth (Slight variations may occur) ★ Materials: Outer fabric, cotton linen (cat pattern) *There may be nep (slubs), small print defects, etc., characteristic of natural fibers. Cotton 100% (striped pattern) Lining, aluminum cooling/insulation sheet (4-layer structure: mesh fabric, aluminum sheet, non-woven fabric, polyester cotton, made in Japan) *We recommend washing in a net or by hand. *Do not use a dryer (tumble dryer) or iron on the thermal insulation sheet. ◆ Ice Pack Case (without elastic, 1 piece) (Photos 9-11) ★ Size: Approximately 12 cm in height x approximately 9.5 cm in width (Slight variations may occur) ★ Materials: Outer fabric, cotton 100% (arabesque pattern) Cotton linen (cat pattern) Lining, cotton 100% (double gauze) *Each item is carefully made, but as it is a handmade product by an amateur, there may be distortions, misalignments, and slight size variations. *If you are looking for perfect sewing, please refrain from purchasing. *Thank you for your understanding of handmade items. *There are no smokers or pets. *It will be shipped folded.
