Setup, Compatibility & Care
To maximize the lifespan of your Hello Kitty Lunch Set, rinse the aluminum bottle thoroughly with warm soapy water before the first use. Always ensure the spout is clicked firmly into the locked position after filling to prevent accidental leaks. The backpack can be spot-cleaned with a damp cloth; avoid submerging it in water to maintain the structural integrity of the insulation. Do not place the aluminum bottle or the sandwich box in a microwave or dishwasher, as high heat can damage the materials and the exterior graphics.
