Borosilicate glass meal-prep containers with three internal compartments and an airtight matte black lid. Set is designed to keep proteins, fats, and low-carb vegetables separate until reheating, preserving texture across two to four days of refrigeration. Glass body is microwave, oven, freezer, and dishwasher safe; lids are top-rack dishwasher safe. The matte finish resists fingerprints and stays cohesive with a dark luxury kitchen aesthetic. Useful for batch-cooking ketogenic meals, packing portion-controlled lunches, and storing macro-tracked leftovers without flavor transfer. A practical upgrade from soft plastic containers that warp, stain, and absorb odors over time.
