What was once a single-use perrier bottle has now been transformed into reusable tumbler glass for any purpose! The vibrant green color in this 4 Pack of upcycled tumbler glasses pops against any icey summer drink. Most importantly, you can maintain your peace of mind knowing that the glass is helping the planet–All of The Green Glass Company's glasses are made in Wisconsin from recycled or upcycled glass bottles in an EPA Green Power Partner facility, helping to save energy and reduce waste!
