I am in love with my Flip-and-Go Stainless Mug. I got the vibrant  purple. The color is so bright, and easy to spot.  Keeps my coffee warm for hours.  It also keeps my ice  water, ice cold for hours. It is the perfect size. Made of high quality materials that will last a lifetime. I highly  recommend this stainless steel flip and go for all your drinking needs. It also makes a great gift.
