Mason Jar Drinking Lid
This device turns canning jars into hipster-y beverage cups.
What You Need To Know
This thick, BPA-free plastic lid is designed to turn regular and widemouthed canning jars into spill-free drinking vessels. Simply secure the lid in place with a metal canning band and pop a straw into the raised diamond-shaped opening (which can also be used for sipping). However, we found that this hipster-y product wasn’t especially practical. Tightening the band around the lid did create a leakproof seal, but unlike with many conventional water bottles, this lid’s opening cannot be closed to stop spills. What’s more, it can’t transform a jar into a hot drink mug; the plastic lid is heat-resistant, but the glass isn’t insulated and will burn your hand. We’ll stick with turning canning jars into tumblers, not thermoses.
Everything We Tested

- Ease of Use: 3 stars out of 3.
This reusable lid turns a Mason jar into a tumbler and proved easy to use and clean. The diamond-shaped “Straw-Tek” opening fits a thin plastic straw. Unfortunately, using a Mason jar as a travel mug doesn’t quite work, since the glass lacks insulation and will be too hot to hold when filled with a hot beverage. Also, the opening doesn’t have a closing mechanism, so it can’t be sealed for transport.
