Concealer Blending Brush Quality control issues 3 I use this brush regularly and it applies both concealer and cream shadow nicely. No shedding, easy to clean, holds it's shape (5 years later). Check the brush upon purchase- Mine was defective. The hair portion had not been attached to the wooden handle. Purchased directly from Bobbi Brown so it is an authentic product. Had issues returning it (purchased in Toronto, live in BC), so ended up super gluing it together myself. These brushes can be wonderful when you get one that's up to quality control standards but, from other reviews and my own experience, it's very hit and miss. I love the make-up and reorder faithfully but these brushes are a sore point in the brand.
