I use the 228 for so many different things.
Applying cream e/s as a liner ( use the tip)
Putting cream e/s or wet pigments in small places or I just it just to apply very little of a product.
It's also a great concealer brush
Perfect for applying cream hightlighters under the browbone.
It is also a great lip brush
I just bought one last week. The MA showed me it is perfect to smoke up an eye look w/a dark shadow. Perfect to apply an outer V of carbon and then blend into existing eyeshadow look. I tried it and it works awesome for this! Hth!
you can use the 228 to apply cream products, such as paints or CCBs if you don't want to use your fingers (i think CCBs suck tho, so don't use them) or for applying shadow on the inner corners of your eyes (or other "hard to reach" spots)
u can use it to apply paints with if you have smaller eyelids. i have smaller eyes, but the 242 is better in my opinion, since it's more versatile (you can use it to pack on color as well as apply cream-based product)
