New, unused Hulk protein shaker. It has a spring inside, making it easy to dissolve even hard-to-dissolve protein powders smoothly without clumping. BPA-free and dishwasher safe. I ordered it from overseas and stored it at home, so there are some minor scratches, but I swear I have never put my mouth on it or mixed protein powder in it. It's a new, unused item. Those who are particularly concerned about cleanliness can rest assured when purchasing.
