Texans are loyal shoppers, so it was only a matter of time before this happened.

Whataburger.com is selling 30 oz., stainless steel tumblers modeled from their in-store Styrofoam cups. You can also get one without the orange and white, but that's no fun.

It's a chance to show off your Whataburger pride for $42.99. The tumbler is not dishwasher safe, so you'll have to wash it by hand. You also may want to grab 'em while the getting is good, because sometimes they run out of stock. As mentioned above, they also offer the same tumbler with the stainless-steel finish.

The best part about these tumblers may be that fans are bragging online about how they keep ice frozen for more than 24-hours. We'll have to do our own field test on that one.

Enjoy!
