Finally, a sieve for these newfangled shower drains ...

Recommended retail use recommendation:

We have our shower drain a silver delusion that we have just raised. Among them were 3 screws on which put this. We have carefully punched in the Abflussieb with a punch on exactly these points etwqs wider holes. Then the screws out, sieve it and purely screws again. So the screen was the same non-slip and close to the drain. You could even attach the bezel back - but stupid for the filter-cleaning, therefore we have the same omitted.

Very useful part! :-)

Personal note at the end:
Who came up with only this stupid shower drains? Certainly not long-haired woman ...
