For the toolheads, I purchased "custom" calibre plastic labels -- e.g., ".45ACP" -- for each of my 11 different 550b toolheads. To store them I have a piece of 1" x 10" pine, on rubber nubs, resting on floor with commercial holders -- both from that ubiquitous "e-" online auction site. My reloading room is in unheated basement, and I do NOT cover them -- the ten in described holder on floor, or the one in use in loader. My reasoning is any, say, dust is less of a worry than affects from moisture. As an added btw, while each has a Dillon powder measure as part of it, I empty ALL powder from each immediately after use -- replacing it with a 3"x5" card on which I use a Sharpie to note powder, date, bullet/weight used, and measured amount. I'm too hurtin' (knee) right now -- but if I can make it down later I'll try and snap/post a photo.
