The sushi trays are available in two sizes and are supplied with a fiiting lid. The sushi trays are made of compostable bioplastic. This material called PLA is made from corn starch and is transparent by default. Carbon is added to the black sushi trays. The sushi trays can be bought from a single box to a full pallet. The trays are strong, have a transparent lid, but are not suitable for hot dishes. Perfect match with our bamboo chopsticks and little portion pots for the ginger and soy sauce.
