I have some of these. Nature's Child (brand) Berry Squeezers, 100% fruit. This is a platypus-like squeeze container full of apples or berries, and it is only 3.17 fluid ounces. You buy it at the grocery store, then squeeze and eat the contents. You rinse out the container and now you have a 3.17 fluid ounce platypus-like thing just right for filling with an adult beverage. Yes, that is on the small side.
