There are glass and plastic airtight containers available for sale, but which one to get depends solely on your preference. Plastic is the most common material for rice and cereal dispensers since it can stay lightweight despite having a large capacity. If buying a plastic rice dispenser, it is important that you get one with food-grade plastic or BPA-free plastic. Most plastic containers are dishwasher-safe, however, some models don’t have an airtight seal.  If you can’t be sure that your rice dispenser is made of BPA-free materials, it's best to go with glass. Glass doesn’t have any chemicals, is much safer to use, and usually has an air-tight seal. A glass airtight container is also much prettier to look at when placed on your counter. They are easy to break, however, and are heavier than their plastic counterparts. Aside from glass and plastic, there are also dispensers made using stainless steel. One popular stainless steel rice dispenser is the CookMax rice dispenser, which combines elegant looks with great functionality.
