Each year 100 BILLION single-use cups end up in landfills. Make a change that's practical and do-able because there's really no excuse for single-use. These cups are made with organic bamboo - a renewable, sustainable fibre that's naturally sterile. Each cup comes with a spill-proof silicone lid and sleeve. They are dishwasher safe, vegan and BPA free. If cared for properly, they can last indefinitely. Not suitable for microwave. See "FACTS" under this collection for more info and care instructions.
