A silver metal lid with a white plastic pump stays true to the iconic mason jar.
Size: The tubes are 5" in length and will reach to the bottom of a pint (16 oz.) size jar. If you are using a half pint (8 oz.) jar simply snip off the end with scissors to fit. These lids fit regular, not wide mouth, mason jars.
Not sure if you have a regular or wide mouth mason jar? Just measure across the top rim of the jar - not the lid. If your jar measures roughly 2 ½ inches at the top you have a regular jar. If your jar measures roughly 3 ¼ inches you have a wide mouth jar.
Aluminum is 100% recyclable. When you're finish with your pump after (hopefully) years and years of use, simply separate the plastic and aluminum parts, rinse, and recycle!
Will it rust?
The lids are coated on the top and underside, helping prevent rust. However, when the hole for the pump is cut, there is a possibility of rust in this area of the lid. If rust occurs along the top rim of the hole it shouldn't be visible from the top because the pump covers the hole. If you are worried about rust becoming an issue on the underside of the lid, you can add a dab of bathtub caulk around the hole before using. Humid climates will cause rust to occur faster.
