Base shadow brush: I really like this brush; it picks up eyeshadow really well and it blends eyeshadow really well. I also like it because it is super soft.
MUA gel eyeliner. The application of it has vastly improved because of this brush.
You can get from Boots(£21.99) but I recommend getting them from Amazon as it is only £17.59 and you can get free delivery.
Have you tried this? What other Real Techniques brushes would you recommend?
