Instead of using petroleum-based plastic which create toxicity and environmental pollution, you can now use our compostable, eco-friendly alternative! Best used for beverages below 110F Should be stored below 110F and away from heat, hot surfaces, and direct sunlight. Items have an expected shelf life of 4-6 months.
