Japanese designer Nobuhiko Arikawa of Rice-Design has created edible tableware for Orto Cafe in Japan.
The plates, bowls and chopsticks are intended to replace disposable paper tableware.
The pieces are made from hardtack, a biscuit dough made from flour, water and salt which was traditionally used as dry emergency rations at sea.
The biscuits will last for months as long as they are kept dry.
The pieces have been put into production by Koratt bakery and cafe, and will be exhibited at Designing10 in Fukuoka, Japan, from 25th to 29th April.
