Designed for storing, freezing, heating, and serving food (lid not oven or microwave safe). Glass is safest for food with no leaching or contamination. 

Highlights:

• Scratch, stain, and odor-resistant tempered glass.
• Water-tight and air-tight lid with integrated silicone seal.
• Easy to open and close the snap-lock lid - passed the 'use' testing machine over 3 million times!.
• Tempered glass is five times stronger than normal glass - designed to go through temperature extremes, if broken it shatters into pebble pieces rather than shards, lasts longer, and does not become fragile with use.
• Oven safe up to 230°C (glass base only) and microwave safe without lid (remove lid before heating). 
• The Top-rack dishwasher is safe. Freezer safe.
