These cans are perfect for “leftover paint” when your project is done. If you have a third of a can or less of paint left in the original metal can it’s going to harden within a year or two. The can lid will probably rust inside the can and ruin the paint inside. Plus, a gallon can is, well, four times as large as a quart! Think about that from a storage perspective.Use these excellent plastic quart-size cans to keep that leftover paint fresh for a long time. I had five different colors in five metal gallon cans of leftover paint from a whole house project. I saved a quart of each color using these plastic cans. They will not rust, they are airtight, and are sturdy.Yes, other reviewers complain that the lids are difficult to get on. They are not with a good hard rubber or plastic hammer. With a light, clean tap the lids click on very nicely. I am very happy with these cans. If I only need a blushful or two of paint out of one of these plastic cans, I have saved the cost of buying another whole gallon two years later because the original paint had dried out because of being left n the original metal gallon can.Also, remember to keep paint in a temperature stable location. That means not in your garage or shed! Temperature extremes will quickly ruin paint.I highly recommend these containers for any appropriate job. Use the correct tool for sealing the lid and rest assured they will close perfectly. One note – if you have no hard rubber or plastic hammer, use a piece of hardwood laid across the lid and lightly tap the WOOD, not the can, to get it to click tight. [...]
