I put them in a small wooden crate I got at the Dollar store. They're displayed on a shelf above my TT, but frankly I haven't looked at the since around your marrow.
@Tys1 I've kept them in the sleeve so far but always wondered if they might cause any warping. Might remove them as well and find some place else for them.
Bathroom.... came in handy during the great toilet paper shortage of 2020. Seriously though, I just leave them in the sleeve and only sometimes read them, if ever.
