Reddit mentions of STORi Clear Plastic Multi-Level Makeup Palette Organizer

Here is the one I have. You could probably fit your whole collection in here.

I thought this might be helpful for others who are tight on space. Welcome to my 46 squarefoot closet.
This is everything I used for the vanity, but feel free to ask about other stuff in the pictures.

• IKEA Storjorm Mirror with built-in light- This mirror has been great. It does need to wired directly into an electrical box; I think there's a workaround for that but I'm not sure.
  
  
• BESTÅ Shelf unit with glass door - two of these bolted to the wall. Super easy to put together and put on the wall. They've been sturdy even when I forget to not lean on it. I do wish I had a glass topper to protect the top shelf from spills. These work particularly well because of their 7 7/8" depth. The unit only sticks out maybe an inch from the door jamb and was the shallowest thing I could find.
  
  
• Acrylic Organizers from Amazon:
  Lipstick,
  Tri cup organizer,
  3 Drawers,
  Multi level palette,
  Nail polish
  
  I find the lipstick organizer to be kind of narrow. KVD bullets don't fit in it, bummer.

So this isn't exactly vertical, but if you have a smidge of desk space, this fits all of my eyeshadow palettes (except for my two Z palettes with singles/depotted eyeshadows). While looking for the link, I came across this one as well, which has a deeper last row so that you could confidently put longer palettes standing on their end (I don't have any issues with my organizer because the palettes hold themselves upright).
