Nice shape and color
October 26, 2013
I like Kartio medium tumblers and use them everyday. They are very sturdy and good size for juice or V8 at breakfast. Sea Blue color is great, but you can see some strain around the edges in this color. I bought two sets, and two out of four has some strain. Sea Blue is softer to keep shape during cooling down than other colors. Anyway, I love this color and have several items from Kartio lines. You cannot find any strain in mouth-blown Kartio Sea Blue items.
Cons
- Some strain only in Sea Blue Medium Tumbler (My Sea blue Large Tumblers and mouth-blown litems have no strain at all.)
