Can place all different kind of spice bottles. These shelves are only good to look at, they do not seem sturdy enough to hold much of anything. And, if you are not sure that this is you. Super recomendo. So I ordered an 8. Nothing more inconvenient than using a can of green beans as a page weight while trying to hold your cookbook open. I ordered this in an X-Large and should?ve gotten a Large. I use them fitted with Comply foam tips. I bought similar slippers at LL Bean. ************************************************************************************************************************************I receive my products in exchange for my unbiased opinion and I take this responsibility seriously.
