I love this shaker cup. It allows you to remove the straw and half a leak proof seal so that you can mix your drinks in the cup (my go to is iced coffee, yum!) once you've shaken it up, you can pop your straw back in. It's great!

I picked these up from cotsco and I really like it. It is great for keeping drinks cold, and not spilling. The colours are fun and summery and came in a large selection.
