@mkoparanova I think I have the other smudger brush you're talking about! I got mine from the vegan travel set that they no longer sell. It's dark blue/grey and has no number. I noticed the same thing you noted when I got the Rose Gold 2.0, that these brushes were different. I don't mind the various shapes, but you're right in that if they have the same name, I would expect the same brush.
I like the face brushes a lot so far! I really like the buffer, I'm glad I waited until they redesigned it to buy it. My one issue is that they made their 228 crease in this set with white natural bristles, whereas before it was dark natural bristles. From the pictures I've seen on the website, it seems like they did this with the regular 228 too. It's just a pity, because I found that brush to honestly be perfection as it was
