These are awesome and they are absolutely beautify. I can't get over how pretty they are. They also do a wonderful job of keeping your drink cold, much longer than I expected. I also love that they can with so many other accessories. The lid is great for when you are outside or for use with the straw if you are inside and are clumsy like I am. Anything that minimizes spilling gets a high rating from me!
I also love that they came with two cleaning brushes. One is specifically for the straws and the other for the cups. These were great additions to the set and make cleaning them super easy.
