Shaker from high quality plastic, convenient system of opening and closing, the total 22oz - it is about 625 milliliters, ie, it is not small. Color as bright as the picture. Shaker Sundesa like matryoshka: Shaker himself plus two compartments of 100 and 150 milliliters, plus a small pill - all this allows you to carry and sportpit and powder and liquid products, mixing everything if necessary. These additional compartments you can withdraw all or leave only one, reducing the size of the shaker. Ring for carrying shaker quite durable and comfortable, it is in the groove, so that does not cling to the bag. Shaker is not intended for hot drinks and food, so that hot water is not recommended to fill it. And so a great option for sportpita for everyday needs: it can be mixed and the dough into pancakes and carry protein. In general, I recommend))
