I actually just got this in today

its plastic as well, but more hard like it appears, havent built it yet. Main reason I did was cause its acid free. Cause i was thinking, im putting stuff in mylar to keep acid away yet I have them in boxes that I know will cause that over time. And I suspect that one day I'll likely "get out of comics" again for whatever time period and I'd to rather know what I'm buying now will be safe and fine for years down the road without having to go check etc.
Besides my cool printed short boxes that I like, I'll gradually replace my regular white short boxes with these if i like them. They stack well too.
