Frequently Asked Questions
Is the glass really explosion-proof in the freezer?
Yes. High borosilicate glass is engineered with very low thermal expansion, which prevents the micro-fractures that cause ordinary glass to crack or shatter in extreme cold, so freezer storage is fully supported.
Are the lids safe around children and pets?
The lids are BPA-free and contain no sharp edges. The four locking tabs require deliberate pressure to open, which makes them harder for toddlers to pop open but easy for adults.
Will the silicone seal leak if the container tips over in a bag?
No. The silicone ring sits inside a channel and is compressed by the four locking tabs, creating a tested leakproof seal even when the container is on its side inside a backpack or gym bag.
Can the glass handle going directly from freezer to a hot oven?
Borosilicate glass is rated up to 752°F, so it tolerates freezer-to-oven transitions far better than standard glass. For extreme temperature jumps, a brief rest at room temperature extends the lifespan.
Does the lid vent prevent pressure buildup when microwaving?
Yes. The integrated air valve releases steam as food heats, which prevents the lid from popping off and reduces the risk of a hot spill in a breakroom or dorm microwave.
Is this safer than storing food in regular plastic containers?
Yes. Glass does not leach BPA, phthalates, or microplastics, even when heated, which is a meaningful safety upgrade for daily-use food storage, especially for families.
How does this compare to stainless steel lunch boxes for safety?
Glass does not impart any metallic taste, does not dent, and is microwave and oven safe, while stainless steel cannot go in the microwave, so glass offers a broader safe-use range for most households.
What happens if I drop a glass container on a hard kitchen floor?
High borosilicate glass is more fracture-resistant than standard glass, but it is still glass. Dropping it from counter height may cause breakage, so handle with the same care you would with any glass bakeware.
I am concerned about glass shards if it does break. Is that a real risk?
Any glass product carries some break risk, but the reinforced borosilicate body is significantly more resistant than regular glass. Most users report years of daily use without incident.
Are the materials food-safe and certified?
The glass is food-grade, BPA-free, and lead-free, and the lid is made from BPA-free plastic with a food-grade silicone seal, so the entire contact surface is food-safe for daily use.
Will the container get too hot to handle after microwaving?
The glass will be hot, as expected with any microwave-safe dish. We recommend using oven mitts or letting it rest for a minute. The vented lid stays cooler because steam escapes through the air valve.
Is the lid safe to use in the microwave?
The lid is microwave safe with the vent valve open. This prevents pressure buildup and keeps the seal from warping, which extends the safety and lifespan of the locking tabs.
Can I trust this around my toddler's highchair area?
The four locking tabs require adult-level grip strength, so accidental opening by a child is unlikely, and there are no small detachable parts that pose a choking hazard.
Will hot soup cause the glass to weaken over time?
No. Borosilicate glass is rated for repeated heating up to 752°F, so daily soup reheating will not degrade the structure or create weak spots over years of use.
How do I know if a container has been damaged and is unsafe?
Inspect the rim and body for chips, deep scratches, or visible cracks before each use. If you find any, retire that container to non-food storage, as damage compromises the structural integrity.
Is the dishwasher high heat safe for the glass and seal?
Yes. Both the glass and the silicone seal are rated for commercial dishwasher cycles, so daily high-heat sanitizing will not warp the lid or weaken the seal.
How do I use the air valve on the lid correctly?
Leave the valve slightly open when microwaving so steam can escape, and close it fully for fridge and transport use to keep the airtight seal intact.
Can I put these containers in the oven?
Yes. The high borosilicate glass is oven safe up to 752°F, but remove the plastic lid before placing the container in the oven to avoid warping.
What is the best way to remove food odors from the glass?
Wash with warm soapy water and a dash of baking soda, or run a dishwasher cycle. Borosilicate glass is non-porous, so odors do not absorb into the body.
Are these containers compatible with standard lunch bags and cooler packs?
Yes, the round shape fits in most insulated lunch bags and the flat lid accepts an ice pack on top for all-day cooling during transport.
Do the lids fit across the different sizes (16oz, 20oz, 23oz)?
No, each size has its own matching lid for a proper airtight seal. Always use the lid that shipped with the corresponding container.
What is included in the box?
Each 4-pack includes four glass containers in your selected size (16oz, 20oz, or 23oz) and four matching vented lids with silicone seals. No additional accessories are required to start using them.
Are these containers safe for long-term daily use?
Yes. The BPA-free borosilicate glass and food-grade silicone seal are both rated for thousands of heating and washing cycles, so daily use for years is fully supported.
Will the lids eventually warp or lose their seal?
With normal dishwasher and microwave use, the lids maintain their seal for years. To extend lifespan, place lids on the top rack of the dishwasher and avoid direct oven heat.
What is the difference between borosilicate glass and regular glass containers?
Borosilicate glass contains boron trioxide, which gives it a much lower thermal expansion rate than regular soda-lime glass. This means it resists thermal shock, handles extreme temperatures, and is far less likely to crack from freezer-to-oven transitions.
