Reusing old food containers is not just about saving space. It is more about saving money, time, and sanity. TikTok creator @SuzieQssss found that peanut butter jar lids fit many other containers, solving the age-old problem of missing tops.

Food containers often end up lidless, useless, and tossed in the trash. In the video, the woman flips that idea on its head when she shows how peanut butter jar lids fit a range of other jars. She twists one onto a tall glass container, and it screwed on like it was made for it.

This alone solves a common kitchen headache. You get a perfectly usable jar back without the stress of hunting down the original lid or buying new ones. It is cheap, easy, and works better than you would expect.

Most people toss food containers when their lids disappear. This TikTok hack keeps them useful. Instead of sending those jars to recycling, peanut butter lids give them new life, fitting tightly on glass and plastic alike.

With Suzie’s lid swap trick, only the jars that match your peanut butter lids need to stay.

However, buying new food containers costs more than people think. A single glass storage jar can cost $5 to $10, especially if it is labeled as eco-friendly or reusable.

Old jars become free storage. With a little trial and error, you will find which ones work with peanut butter lids and start building a matched set without spending a dollar.

Tossed food containers add to the growing problem of plastic waste. According to the World Wildlife Fund, it takes about 450 years for some plastic items to decompose. That is a long time for something that held salsa for two days.

Once you try this with peanut butter lids, you will start looking at every container differently. Spaghetti sauce jars, salsa containers, and jelly jars suddenly seem more valuable.

Instead of tossing them out, you will test each one. This simple habit helps shift how you view trash and reuse.

Unlike many plastic lids, peanut butter jar tops are thick and sturdy. They don't warp as easily in the dishwasher and can take some wear. That makes them ideal for reuse.

You will get more spins out of them before they give out, and because they are all the same size, once you have got a few, they will match across multiple jars.

If you have kids, this is a hands-on way to show how reuse works. Let them help test which jars fit. Make it a game to find matching lids around the house.

The lesson sticks better when they are part of the process. And when kids learn that not everything needs to be thrown away, they carry that mindset forward. Food containers that are reused tend to get labeled more often. It is easier to write “Rice” or “Craft Beads” on a container you trust not to spill.

Glass jars take stickers and marker labels better than most plastic tubs. Once you have a working lid, it becomes more than a random container—it becomes part of a real system.
