There isn't a ton to add to my original review, because the Mini Brush Tree is just as amazing as the original. It actually holds even more brushes - it has 24 holes, vs. the original's 14 - despite being only about 3/4 the size. It does work better for my thin-handled brushes, as I'd hoped! About 90% of them fit perfectly into it with just one in each hole. The only slight trouble I found was with the REALLY thin-handled brushes (such as my MAC 209, 210, and 211). They will stay in holes of the Mini Brush Tree alone, but sort of tilt sideways, which made me worry they would bump into the base of the Brush Tree or other brushes and splay the bristles. However, I was easily able to fix this using Jan's trick and just putting three of those tiny ones in one hole together. Problem solved!
Here you can see my entire brush collection, which is a little over 50 brushes, drying in my two Brush Trees - the Mini on the left, Original on the right. I still double-up on some holes with medium-sized brush handles even when it's not necessary, just because it takes less finessing to get them to stay upright and I can kind of shove them in there (haha) and move on; this also makes it possible for me to dry all of my brushes upside-down at once.
I highly, highly recommend both of these Brush Trees. They may not be a "must-have" for everyone, but now that I have them, I can't imagine being without them. If something happened to mine, I would absolutely repurchase both without hesitation and with my own money. They are a fantastic and functional tool for any makeup artist or hobbyist. You can purchase these together in a value set (and save $10) or separately on Benjabelle's website. I can't wait to see what Benjabelle will come out with next!
