I’m not sure quite what I expected but I guess I thought it may have some type of metal or insulation to keep your drink cold hence 4 stars but that aside it’s actually a pretty nice plastic cup. It’s a pretty large size and comes with the reusable plastic straw that has the little extra wider piece towards the end to keep it inside the cup should it get turned over. The lid screws on keeping its contents safe although I would imagine it might still leak if nothing else from the entry point of the straw. It’s top row dishwasher safe and has the little Keurig logo on the front in white. The ‘glass’ itself is clear. Nice for summer days.
