We all know that one person who tries really hard to make good welds but is still...umm...okay. Well we have a cup for them. And yes this cup is just...okay. And I know my welding skills aren't top notch. But that's the point...right? :) This 20 oz has been made to look rough and like it's seen it's better days. But the cup itself is sturdy, it's a double wall insulated stainless cup that is made of 18/8 food grade so it will keep you drinks hot and cold for hours. These are hand wash only.
