Firm spout for baby bottles.

Suitable for all threaded rings on standard bottles. The drinking aid has a drop-free valve which opens during drinking and then closes again automatically. The valve seals the bottle from the inside thus reliably preventing spills. The extra-flat lip support facilitates comfortable drinking. Not suitable for use with fibrous liquids like juice - as this will clog the spout.

The product description of this spout is oh so German, nothing like Germans to get to the point.
