Glass Food Storage Containers with Silicone Glass Lids, 6 Pack Square Airtight Meal Prep food container, Leakproof Borosilicate Glass Bowls Set, Microwave, Oven, Freezer & Dishwasher Safe

Q&A:Q1: Are the lids safe to put in the oven?A: No. While the high-borosilicate glass base is oven safe up to high temperatures, the tempered glass and silicone lids are not meant for oven use.Q2: Can I use the lid in the microwave?A: Yes, the tempered glass lid is microwave-safe, but you must open the silicone air-release valve first. This allows steam to escape safely and prevents pressure buildup or lid popping during heating.Q3: Are these containers completely plastic-free?A: Yes. The container base is made of 100% borosilicate glass, and the lid is made entirely of clear tempered glass and food-grade silicone. There are zero plastic clips, tabs, or linings, making it an eco-friendly, non-toxic food storage solution.Q4: Are the glass lids and silicone seals dishwasher safe?A: Yes, both the glass bases and the silicone glass lids are dishwasher safe. Unlike plastic lids that warp or harbor grease, the tempered glass and silicone materials retain their shape and clean easily without clouding or staining.Q5: Can these containers go straight from the freezer to the microwave?A: The borosilicate glass body is thermal shock resistant. However, to ensure long-term durability, we recommend allowing frozen containers to sit at room temperature for a couple of minutes before reheating, and always unsealing the air valve before microwaving.Q6: How do I seal and open the airtight silicone lid easily?A: To Seal: Place the lid on the bowl with the air valve open, press down firmly around the edges to push out excess air, then push the valve plug down to lock in the airtight seal.To Open: Simply pull open the silicone air valve plug first to release the vacuum pressure, and the lid will lift off smoothly.
