BOROHOUSE Borosilicate Glass Food Storage Containers

Yes, the borosilicate glass is designed to withstand extreme temperature changes, ranging from -4°F to 950°F. However, it is always best practice to avoid extreme thermal shock by letting frozen items sit at room temperature for a few minutes before placing them in a preheated oven.

The glass bases are dishwasher safe, but we recommend hand-washing the lids to preserve the integrity of the airtight seal. When microwaving, the lids are safe to use as long as you open the steam release vent first.

Yes, the lids feature a secure, airtight locking mechanism designed to prevent leaks and spills. This makes them reliable for transporting soups, sauces, or dressings in your bag without worrying about messes.

The glass material is non-porous and odor-resistant, so it won't hold onto smells or stains from previous meals. While the plastic lids are durable, they are more susceptible to odors if left unwashed for long periods, so we recommend cleaning them promptly after use.

The containers are designed with stackable shapes that nest efficiently in your fridge or pantry. This modular design helps you maximize vertical storage space, keeping your kitchen organized and clutter-free.
