What does your cup say about you? These cups, made from FSC certified paper, say a lot. They say you care about the environment because the paper comes from sustainably managed forests. These cups also have a leak proof bio lining, which makes them compostable within 3-6-Months in a commercial composting system. With simple steps like these, we can make a big impact. Both the cups and the bag they come in are 100-percent compostable! We donate 25 Percent of profits to grassroots social and environmental organizations.
