This joyjolt tumbler is the best. I have a black one and its beautiful! Stickers stick to it if you are into that. I use this cup everyday, theres nothing better then always taking a sip from it and its still ice cold from hours ago! even over night i wake up and theres still ice at the bottom. There inter changable lid is also great, i love that i can sip a cold drink with the straw or change the lid so i can put something hot in it.
