I suggest you choose the latter: Bonnie in Germany. I think BOONI is superior in thermal insulation performance and detail design. After all, it is a German product technology, which is very humanized. Let's take the insulation effect as an example. Let's talk about the difference of heat preservation performance first, not simply compare the heat preservation time. Now the common insulated lunch boxes on the market, including Supor's, have layered design, but the insulation effect is not layered, and Buni's insulated lunch box's insulation capacity is gradually strengthened from top to bottom. The first and second floors can be used to place cold dishes and hot dishes, and the third and fourth floors can be used to place rice and porridge soup, which can meet the different temperature requirements of different foods.
