[Vocabulary] Top/Middle shelves

[newkeenlearner]

I am not sure about my third sentence. Could you please correct me?
The most expensive items are on top shelves.

The most expensive items are on middle shelves.

The most expensive items are on low shelves.

The word you need there is "bottom". However, you may need the definite article ("the") after "on" in those sentences. Can you describe the context in which you intend using those sentences please?

I would certainly say the definite article is needed before "top". Without it, you could use "high shelves".

Thanks so much.
The whole sentence was what I wrote.

I am really sorry when I transfer sentences here from my book I leave some words out. You are right we need "the".
The most expensive items are on the top shelves.

The most expensive items are on the middle shelves.

The most expensive items are on the bottom shelves.

Thanks.
