EcoJarz was started by a group of friends who also happened to have a lot of mason jars at home. Between canning tomatoes, fermenting kraut and storing bulk grains there were jars all over the kitchen. It was only natural that all of them, like so many others out there, would constantly end up using the jars as drinking vessels too.  One fateful day in the winter of 2012, Kirby, who is always full of ideas, called a meeting to show off a simple invention.  In his hands, he had drawings of a stainless steel lid to convert any mason jar into a reusable, plastic-free to-go cup.

They flipped their lids! And who could blame them? Now their jars could be legitimate water bottles and veritable coffee mugs. Best of all – using a stainless steel lid to fit standard and ubiquitous jars meant no more plastic coming in contact with food and no more expensive branded water bottles! Instead they had a high-quality product that could be used jar in and jar out. 

The formula was simple and irresistible: Stainless Steel + Glass = <3
