Show off your Sig Kap mama pride with these stainless steel insulated tumblers in our Moms Have More Fun Bright design. This 20oz skinny tumbler with vacuum insulation technology and BPA free slider, splash resistant lid and both metal and plastic straw, is powder coated which gives you more of a solid grip when holding your beverage, plus the vacuum insulation keeps your favorite drinks icy cold or piping hot for hours. We recommend to hand wash these only.
