Peacock Magic Bottle Industry Hello Kitty Insulated 3-Tier Lunch Jar Height: 16.5 cm Bottom tier (rice): 5.3 cm Middle tier: 4 cm Top tier: 2.5 cm Heat retention: 8:30 AM (boiling water) 70°C - 1:30 PM 45°C; it felt sufficiently warm to the touch. Thank you for viewing. This item is from about 20 years ago and shows signs of use. I used it for about 2 years and found it stored in a Ziploc bag on the kitchen shelf, so I disinfected and cleaned it (including the bag) for this listing. Since it's quite old, there is overall wear and tear, and the semi-transparent lid of the top tier container has some yellowing. Also, the pink parts of the jar's fasteners are yellowed. The bag has faded, and there are areas where the zipper coating has peeled off. Please check the photos for details. The heat retention function seems to be working fine, as measured with a thermometer. I hope someone who understands the above will use it.
