The Star Ascent Stainless Steel Insulated Tumbler holds 30 oz. and has double wall vacuum insulation so hot drinks stay hot for hours and cold drinks stay cold for up to 24 hours. I have been using this cup as my to go cup ever since it arrived as it is so fantastic at keeping iced drinks cold. The tumble does not sweat or produce condensation and it comes with a great no spill sliding lid. The tumbler also fits into my cars cup holder so it is perfect for road trips.
I received this product for free or at a discount in exchange for my honest and unbiased review.
