I love this brush! Sometimes when I travel I can't bring all of my brushes with me (even though I want to) and I love that this one retracts, so it's easy to throw in your purse in case you need to freshen up on the go! I love baking my Laura Mercier setting powder with this brush; the coverage is really nice.
Retractable brushes are lifesavers. This one by Stilla is so handy! I keep it in my purse for when I need to touch up. I can say that I use it daily along with other brushes that I keep. It's bristles are not rough, they do great on my skin! Go try this out.
