Review on 📦 Set of 4 Extra Large Food Storage Containers with 5.2L Capacity (175.9oz) - Airtight & Leakproof - Includes 4 Measuring Cups + Labels - Perfect for Sugar, Flour, Baking Supplies - Clear Plastic by John Sharma

Great product! I've bought other products with a similar design but these containers are HUGE and very well constructed and I can tell you they outperform measuring cups in the sealing area and that's a huge plus. Sometimes you need to push the lids into the container to ensure a secure seal before inverting the valves to seal them. The tightness of these White Feather airtight containers is excellent; It fits tighter than Oxo's pop-up lids and I feel like the vacuum mechanism at the top of the White Feather jars is responsible for a good vacuum seal. Overall, White Feather's containers keep my dry cereal, grains, cookies, rice, soil, etc. fresher than any of my Oxo containers or other similar containers I've had in the past, and they've all been so much better than other supposedly ant-proof ones Containers I have tried and returned. Measuring cups are perfect, 4 are included so I can have one for each container. Questions I had before purchasing: * Is this product BPA free? Answer: YES* Are these containers modular and stackable? Answer YES, for perfectly clean panties, stackable containers are important to me* Are these lids interchangeable? Answer YES* Is it dishwasher safe? Answer: YES, I've washed it in the dishwasher without any problems, I haven't tried the lids yet.* Can this product be used in the microwave? Answer: NO* Can these containers be frozen? Answer: YES* Is this product sealed? Answer: YES* Are there additional services in this product? Answer: YES, many Amazon products now have some additional features. The great thing about this product is that it comes with two extra labels and a marker - a great plus, save $9-10 on these measuring cups, which are also $9-10 separately.
