 Due to the different coefficient of expansion between stainless steel and PP materials.

 Sudden changes in temperature can cause the gaps between the two to widen, leading to water intrusion.

 So please do not boil in boiling water, and do not put it in the microwave.

 If you need to disinfect, you can use tableware cleaning disinfectant.

 Please do not soak in water for a long time. If the bowl gets wet, just turn it over to dry.

 This bowl is made of double layers, with a stainless steel inner and an outer layer of PP. It is pressed from two-layer molds, as the expansion coefficients of stainless steel and PP are different.

Sudden changes in temperature can cause the gaps between the two to widen, leading to water intrusion.

 The water entering the middle of the bowl is a normal phenomenon. Since stainless steel and plastic cannot adhere to each other, the bowl will not be glued, and it is designed for the health of babies. Using glue will be counterproductive. Therefore, if you cannot accept this phenomenon, please do not purchase. This is a normal phenomenon that does not affect the use of the bowl. To avoid this, the method is to avoid using cold water when cleaning and to use warm water instead. And do not use steel wool to clean, but use cotton cloth as much as possible.。

 Please note: Do not heat in the microwave oven, and do not disinfect in the disinfection cabinet!
