First of all, I owe a huge apology. I learned about painting these tumblers from another blog, and I cannot find the source. I do so want to give her credit, so if anyone has an idea of where I got this idea, I'll edit my post to give that blog proper credit.
Okay, so if you love a cold (or hot) beverage, you will want to look for stainless steel, double wall, vacuum insulated tumblers. Yeti brand has cornered the market as the "cool brand to have," but -- and this is huge -- the Yeti brand comes with a Yeti price tag. That price tag does not necessarily mean that the product performs better. As a matter of fact, the Rtic brand does everything the Yeti does. Beverages keep their temperature for hours in these wonderful tumblers.
Instead of spending $99 for a glitter ombre Yeti, I spent $18 for the plain stainless steel 20oz. tumbler and spray painted with Rustoleum Americana paints. It takes several layers, plus drying times in between. I then sprayed one coat of glitter and sealed it with several coats of polyacrylic sealer. It is not food safe, but that's okay because I use a straw instead of drinking off the rim.
It's a time-consuming project, but well worth it. This tumbler is wonderful and every bit as dependable as the Yeti! Even with the cost of all the sprays and sealer, I still saved money and have paints to do dozens of more projects!
