They are environmentally friendly, BPA-free and non-toxic, and can keep your food fresh for a long time. Leak-proof-the snap-on lid provides a tight, leak-proof seal to maintain freshness and prevent food leakage and spillage. They are very suitable for work, school, picnics, camping, etc. Please do not use these containers in the dishwasher, as they will gradually deform the lid and no longer leak proof. Save space-The set includes three containers of different sizes, which can be easily nested in each other to save space in the kitchen cabinet when not in use. They are also easy to clean. Non-slip exterior-The exterior is made of non-slip material, which not only prevents slipping, but also perfectly isolates heat from hot food so that your hands will not be burned. The perfect choice for portion control-wrap it with ribbon and give it to your loved ones so they can enjoy healthier homemade food!
