Retro Wave Tumbler - 12 oz.

I like everything about my Blue Retro 12oz cooler, except it wont keep anything cold for a half an hour. I like the size, feel/shape, appearance, simple lid, and overall construction. I was forced to buy a Thermos brand 16oz all stainless which keeps your drink cold for hours, with or without ice, but with it's eight and very narrow base it falls over when you just look at it! My wife's older Thermos 16 is more stable, does not have the extreme taper and still fits in the car holders.
I don't use it! Disappointed, Larry

It is a gift for my secret sister and it arrived just as nice as I expected. Now to gift my friend.

I purchased my 12 oz. Retro Wave Matte NCBlue Tumbler in March 2025.
I like everything aboutmy tumbler, except It will not keep my cold coffee cold in my car for the 2 hours I spend in physical therapy.
My wife"s Thermos brand real vacuum 16 oz tumbler is far superior
so I now have to buy a Thermos brand. Themos does not make a 12 oz.
Your card attached to mug said Vacuum construction and your website says triple layer vacuum construction. I think it is not really true vacuum or it would work better. I am going to ppurchase the Thermos 16 oz, and I plan on prying open your mug to see exactly what insulation you have in there. Sincerely, Larry N. retired construction engineer, Miami, Fla.

I purchased one years ago and have used different brands. However, the travel mugs seem to grow in size and they don’t fit in my car! I purchased two new ones and they are just the right size! They are easy to carry and I really like the way the mouthpiece is contoured. It keeps me from burning my lips when I have a hot drink. I hope these are around for a long time!

retro wave tumbler is the perfect coffee cup for on the go ! I loved it so much I ordered 5 of them !
