I've created this sign for a bathroom in a property that I rent out:
(And yes, before you ask - I have fished several such items out of toilets in the past.)
Is the wording correct? I'm particularly uncertain about не vs. нет, but any other pointers would be appreciated.
Edit: my apologies for not reading the site rules carefully, and thanks to those who provided constructive comments. As one of them is that I shouldn't have posted just an image, but rather the text, here it is:
Пожалуйста, поставьте только туалетную бумагу в туалете! не влажные салфетки детские салфетки бумажных полотенец пластик игрушки и т.п.
For comparison, I have the same sign (with the same layout) in some other languages, such as English:
Please put only toilet paper in the toilet! NO wet wipes baby wipes paper towels plastic toys etc.
...and so I'd like as much as possible to keep the same flow. If indeed it's not idiomatic Russian to give a list with не/нет followed by a number of items, then so be it. But I would wonder: you find, for example, apartment buildings in the U.S. that have such signs outside (NO in large type, followed by a list of things not to do: ball playing, loitering, etc.); are such signs unknown in Russia?
