The label says "KEEP HOT/COOL BEST BEFORE 5 HOURS," indicating that it can keep things hot or cold for about 5 hours. The inside is covered with urethane material. Also, there's "0.9 LT." on the bottom, which might mean it holds 0.9 liters, but the details are unclear. The color scheme consists of primary colors: yellow, green, and blue, so children will likely enjoy it. Although it's unused, there's some tearing in the vinyl (see images 7 and 8). It will be shipped directly in a plastic bag without any cushioning. Body size: Approximately 26.6cm high x 11.3cm wide x 9.5cm deep / Made in Thailand Please read the profile before purchasing.
