What I love most about it is that these containers don’t stain or scratch. Personally, I have no taste for storage boxes that leak or stain easily because cleaning after is an exhaustive job.

In addition, they offer a wide range of choices from food storage to prep, and mixing containers. They also have lock canisters to tiffin boxes, shakers, bottles, and tableware too apart from their trademark containers.

Coupled with their portability, airtight sealing, stain-resistance, and lasting freshness, nothing else even comes close to these premium storage boxes!

What About Dishwashers

Glasslock bowls are safe in the dishwasher. Nevertheless, you need to stick to low-heat cycles when dishwashing to prevent any damage.

In short, toughened glass boxes can go from freezer to oven, microwave, and back again without a hitch. But that’s only if you take care not to expose the container to extreme temperature variations suddenly!

Whether you have a French door or a side-by-side refrigerator, these containers offer a new way to store your frozen foods in the freshest possible manner.

What’s more, they can be stacked up neatly in your refrigerator too!

If you’re wondering are their lids BPA-Free, yes they are! That’s because they don’t contain any Bisphenol-A or other dangerous environmental hormones.

These containers are 100% airtight and leak-proof. That’s because these storage boxes come fitted with silicone gaskets that help it to snap and lock it from four sides. Secondly, they’re easy to carry.

How To Use Glasslock Containers Lids Correctly?
