Can I use my frank green bottles and cups for carbonated drinks?Updated 12 hours ago

We’ve received feedback from customers who enjoy using their frank green reusables with carbonated drinks. However, we haven’t conducted extensive testing on how regular use of carbonated drinks may affect the product or its lifecycle over time, so we don’t recommend using carbonated drinks in our reusables.

If you do choose to use carbonated drinks, you do so at your own risk. As the CO₂ can create pressure inside the product, we recommend occasionally lifting the mouthpiece to allow any built up pressure to escape. Please take extra care when opening your reusable, as built up pressure may cause the contents to release unexpectedly.
