Ware is consuming packaged all the necessary items are individually sealed in sachets, installation and operating instructions is the delivery.
The valve makes a solid and high quality impression and is easy to assemble.
In addition to the fitting is also a complete drainage system for sink included, which I personally would have not needed because mine still was perfectly OK and did not need to be replaced.
I do not know whether it also individually are if not fitting, I thought to offer separate the two items it makes sense, because you have to renew not necessarily the drain with a defective valve - but it pay full price anyway.
But for now, there are products full credit.
