20 oz Skinny Tall Stainless Steel Vacuum Insulated Tumbler with Straw - Crazy Chicken Lady Design (Black) | Perfect for Coffee, Tea & Cold Drinks On The Go | Great Gift for Chicken Lovers

This is my favorite cup I use it every day. I can fill this cup up with ice and water, and even though I have to keep filling the cup up with water, I don't have to keep adding ice. The same ice will last me all day and night. I never go without cold water. My boyfriend dropped it and the only thing that happened was my straw broke. I bought more straws for it. I plan to buy more cups.
