Probably the first time I share my entire room here on the forum, but sure:
Book shelf; three puzzle shelves; two binder shelves; and five of the boxes with duplicated cards:
Sneak peak of the Seviper figures on my desk (I’ll share them soon in detail in my collection thread, as well as the merchandise thread. I’m waiting for some last incoming packages to arrived first):
Two Pokémon-related things hanging on the wall:
And the rest of the room with eleven more twisty puzzle shelves; one more box with duplicates; the box with unordered raw cards; some more twisty puzzles I plan on selling in some boxes; my mineral/gemstones/fossil collection behind bars 
(since most of the stones are pretty heavy, this was at the time more practical than a glass cabinet). Oh, and ignore the closet and chest of drawers made for children. 
They’re almost as old as I am, and I will defintely replace them when I move out. Simply haven’t bothered, since they’re still functioning fine. ¯\_:slightly_smiling_face:_/¯
I use the method described here: putting the graded cards into a sleeve with adhesive fold, and put that fold onto the 4-slot photograph binder page. That way the graded cards can’t fall out. Works perfect imo, although I might need a second binder soon, since this one is getting rather bulky now.
