Hydro Flow 2.0 Steel Straw
The Straw You’ll Actually Keep.
It started with a Tumbler — but even the straw matters.
This little piece of steel helps replace thousands of disposables. It’s smooth, quiet, ocean-friendly, and made to last through years of refills.
And like all things Whalecup, it’s not just smart — it’s made with heart.
Designed for the Hydro Flow 2.0 Tumbler
Our Steel & Silicone Straws are designed to perfectly match your Hydro Flow 2.0 Tumbler — or stand strong on their own. No harmful plastic. No soggy paper. Just sustainable style, built for everyday joy.
