These containers are suitable for both hot and cold foods, and are safe for use in the microwave, oven (up to 220°C for 20 minutes), and freezer. Made from renewable sugarcane fibrous residue using a low-energy production process, the sugarcane fiber is compostable and will naturally break down. The containers are also waterproof and greaseproof, making them an excellent choice for serving a variety of foods, such as soup, congee, noodles, curry, and laksa. Available in three additional sizes (24oz, 32oz, 40oz) and two colors (unbleached sugarcane and white), with matching lids made from RPET, sugarcane, or unbleached sugarcane.
