No more dressing or mustard sauce bowls in the fridge, which was afraid of spilling when you take something off. This shaker can be stored in the fridge or on one of its shelves, as desired. And it is sealed! I find it very well designed and very good quality. Mention BPA, is a little more significant. He unscrews at the green plastic band and is used to pay Ingredients dosing without problem, especially for the spoons mustard! Closes in a jiffy. Once the mixture shaken well, just tilt back the small plastic rod that holds the cap closed. This plug is hermetically sealed with its seal and it only rotates on its axis, so there is no risk of losing it. The spout can fine deliver the desired quantity and avoids sagging along the shaker. Good grip, but it is solid plastic so brittle attention to the fall anyway! It is scaled up to 350 ml and measures about 22 cm high. A slightly smaller model is enough for me but I have only found one. It goes in the dishwasher, and that's just happiness with fatty utensils)
