Antibacterial food dividers and lunch sheets
These are antibacterial products meant to be used with Japanese packed lunches (bento), usually eaten at room temperature. I bought the special antibacterial sushi grass at Nijiya Market in San Francisco's Japantown, and the antibacterial bento sheets at Daiso in Daly City. Not all food dividers/baran are antibacterial; they need to be marked with the Japanese characters in the note above to be antibacterial. Full post on food safety for packed lunches here.
