New member with a pre-purchase question re roof storage

[ilan15]

Hi all,

I'm looking at several low mileage '24s with glass roof panels. I just got this photo of the panels in the frunk, and noticed they seem to be in hard cases, as opposed to sleeves.
Anyone seen this before?

Thanks,

I prefer the sleeves. Hard cases take up too much space. I use my frunk a lot.
