Inspired by traditional Korean ceramics, the hygienic Glasslock Air food containers are designed not only for preserving food but also for serving it right at the table. Manufactured from non-breakable, tempered soda-lime glass, the containers are easy to recycle after many years of use. The airtight lids of the containers can be used in a microwave oven and prevent a loss of moisture in the food when heated, preserving the full flavour of the food.
