Solid Construction - The containers' sturdy PP (polypropylene) plastic construction guarantees a long service life, even when subjected to severe use.
One hundred percent watertight, airtight, and spillproof - Detailing that aids in retaining the containers' contents' freshness over time. The snap-on lock system and silicone rubber lining of the lids work together to keep contents fresh.
The containers themselves (but not the lids) may go through the dishwasher, microwave, and freezer without any problems. In temperatures up to 80 degrees Celsius, they can be used effectively.
Rectangular form facilitates stacking and storage whether in cupboards, fridges, or freezers.

Product Descriptions:

Produced using Premium BPA-Free Plastic
Every single one of the containers is manufactured out of BPA-free plastic, so the food inside will stay fresh and taste the same as it did when you first opened it.

Strong and Watertight Construction
The containers' snap-on lids are leakproof and convenient to use. If you're using a container with a lid of a similar size, you can simply snap the two together. Thanks to all of these features, the set is ideal for stowing away snacks, meals, and other edibles. These containers are perfect for transporting hot meals to loved ones or for giving as a gift.

Easy to clean and store
Both larger and smaller containers can be stacked on top of each other, and containers of the same size can be stacked together. Savings in cabinet depth, pantry depth, and the like can be substantial. Use them, clean them, and put them away for another time with no problems at all.

Very Little Maintenance Required
The containers themselves (but not the lids) are safe for use in the microwave, freezer, and top rack of the dishwasher. This eliminates the need to transfer food to a separate plate before heating it, and saves time. You may avoid wasting a lot of time by doing it this way.

It is suggested that you run water over it before each use.

When using a microwave, be sure to vent the contents by opening the lid or removing the lid from one corner of the container(s).

Make sure to wait a few minutes after microwaving before removing the container(s). Holding the container(s) at both ends will help you remove them.

To ensure an airtight seal, close the lid completely.
