Enviro Lids are a one of a kind, rust free stainless steel lid that convert a regular size mason jar into a travel cup!
The hole which the straws fits snuggly into has a custom designed food grade silicone grommet making it completely plastic free. Whether you are heading to the gym with your morning smoothie, to work with your morning coffee or you just need your toddler to not spill their milk at the dinner table, we’ve got you covered. So many options, one Enviro Lid.
We recommend pairing a Enviro Lid with our glass straws for children under five. This changes the straw from a play thing to a sippy cup.
9.5mm and 12mm straw openings
This lid fits regular size Mason -type jars only, and NOT wide mouth jars.>
