Meal prep just got so much easier and healthier with these glass containers! You get 10 pieces total - 5 large 1040ml containers and 5 small 370ml containers, perfect for everything from main dishes to snacks and sauces. The glass is high-quality borosilicate that can handle extreme temperatures from -20°C to 400°C, meaning you can go straight from freezer to oven to microwave without worrying about damaging them. The lids have four-sided snap locks and removable silicone seals that create a truly airtight, leak-proof seal - no more messy spills in your bag! They're completely BPA-free and won't absorb stains or odors like plastic containers often do. The stackable design saves so much space in your cabinets or fridge, and they're dishwasher safe for easy cleaning. The clear glass lets you see exactly what's inside, and the included label stickers and white pen help you stay organized. Whether you're packing lunches for work, prepping meals for the week, storing leftovers, or taking food to picnics, these containers make everything more convenient. The quality feels substantial and durable - these aren't flimsy containers that will break easily. They're that kitchen upgrade you didn't know you needed until you start using them every single day!
