This set includes 8 rectangular and square glass storage containers in varying sizes from 5 to 35.1 fluid ounce, designed for everyday kitchen use. Made from durable borosilicate glass, they tolerate extreme temperature shifts-from freezer to microwave or oven-without cracking. Each container features an airtight lid with a removable silicone gasket and 4 hinge-based snap locks to prevent leaks and odor transfer. The material is food-grade, BPA-free, non-porous, and stain-resistant, maintaining clarity and ease of cleaning over time. Containers are fully dishwasher safe and stack neatly when nested, optimizing cabinet space. Their transparency allows quick visual identification of contents, supporting efficient meal prep, portion control, and transport for lunches, picnics, or travel. No plastic lining or coatings are used, and the smooth interior surface resists absorption of flavors or discoloration. Lids are designed for secure closure without excessive force, and the glass thickness ensures stability during handling and reheating. All pieces are compatible with standard home kitchen appliances and routines without requiring special care instructions beyond routine washing.
