The bottles look very beautiful and quality made in the kitchen, but the locks are very bad. If you want to remove the transparent cap of the opening, for example, one often has the whole closure in hand. Then you must first separate the two parts and the closure are back in the bottle, so that it can use it. That's pretty cumbersome and unwieldy. He also is the closure (not the transparent cap, special indeed the "pour-part") is not 100% sealed, so that around the opening of the bottle like smeared oil.
