I am going to start investing in more high end brushes - eventually - but; (a) they're so expensive, I'm still smarting over a $38 brush from Illamasqua that I never use but I can't seem to let go, and (b) I really should go on a spending ban because over the last two months I have spent over $1000 on beauty products alone...
I keep my main girls in this really pretty candle holder. These are pretty much all the face brushes I use within a week and some extra. Excessive, but clean. I learnt the hard way that using dirty brushes continually are awful for my [anyones] skin.
The blue container is actually a relic from my younger years. It's a pen container that spins quite well and houses all my other face brushes that I don't use often or are back up brushes.
This collection may seem too much for one face, but I love brushes and once had over 80 odd brushes or so. This set up is very manageable and functional, which is the way I like it. Until I start replacing some with higher quality brushes, I don't think this collection will be changing any time soon.
