I got those first and returned them immediately. It seemed they are intended to be single use. You put ONE item in, lock it closed, and that's it.
Please see the one-star reviews on Amazon.

Those are the ones I ordered. Wife changed from trulicity to ozempic a few months ago, the Ozempic have just a tiny double ended needle cap that unscrews from the pen. These containers appear to be designed exactly for the ozempic as the needle end of them fits in exactly.
