The Kinetic Go Green GlassLock 6 Piece Rectangular Set consists of three 37 ounce rectangular glass bowls, each with fitted lids that have tabs that snap into place. (For an idea of how these glasslock tabs work, see this video which shows how they open and close).

The tempered glass is heavy, solid, stain-resistant and can withstand microwaves, freezers and dishwashers. Please note that the glass is not safe in ovens as it is made of soda lime. The lids are free of BPA. All Glasslock bowls are fully FDA approved.
