My mum bought me a 6 piece pack of Ecotools' brushes for Christmas last year and I've been inlove ever since!
These brushes are 100% cruelty-free, made up of synthetic taklon bristles and have handles made of sustainable bamboo and recycled aluminum. The bristles are incredibly soft compared to other synthetic brands and the bristles don't shed.
They offer a range of different types of brushes and packs to suit everyone. If you spot them in your beauty store I recommend checking them out. :)
