Sigma makes great makeup brushes, but they are pricy. Spend $50 or more at Nail Polish Canada (or Obsessed Canada) today and they will send you a gift of a mini Sigma E25 Blending Brush. I have the E25 and it one of my favourite brushes (for those crazy about makeup, it is similar to the Mac 217 brush). They are super soft and blend eyeshadow really well and a mini is perfect to keep in your on-the-go makeup bag.
Click here to shop at Nail Polish Canada or here to shop at Obsessed Canada (the beauty offshoot of NPC). You need to add the free brush from the pages linked, they will not be added automatically.
Most, if not all, of the items shown on Obsessed Canada are available on Nail Polish Canada (with the added bonus of so much more nail polish). They sell many beauty brands, it is not just nail polish, pick up ELF cosmetics, Batiste dry shampoo, EOS lipbalms, even Dove (although you will find Dove cheaper in stores).
