Which container is best for storing rice and flour? It is said that paulownia is environmentally friendly! It is said that stainless steel is durable! Also said that plastic is moisture-proof! Which is the healthiest? I used lock lock's crisper, and now I use the second one. It is most suitable for storing grain, especially things that are prone to insects, such as rice and noodles. Excellent sealing, effective isolation from moisture, better than the so-called special rice barrel. The handle is easy to take and put. The capacity is large enough, 10 kg of rice only takes up half of the space.
