Fill one with almond butter for your morning snack of apple slices, load the second one up with dressing for your lunch salad, and measure out the perfect number of nuts into the third. (Each BPA-free container holds up to 2 ounces, so they’re great for portion control.) The lids are all easy enough to twist on and off, but are also leakproof, so you can slip them into a bag or even stash them right in the container with your salad. Dishwasher safe. Ensure cap is threaded properly and closed tightly for a secure seal
