I would recommend this product to Seifesieden warmly. Very good value for money. The NaOH dissolves with the slightest stirring problems and forms no lumps, even crystals settle to the bottom of the vessel. The delivery arrived very quickly and in a stable, well-padded package with safety notice. On the subject of closure / lid: It is a small bucket with a screw cap. When unscrewing it (as indeed it is), and nothing will break. ;-)
