I only used brushes 02 and 10 once. These have both been cleaned and dried. From website: Made in collaboration with Katie Jane Hughes, this professional brush set includes 25 (!) silky-soft, premium face and eye brushes, perfect for precise application of your favourite products. Luxe, cream-coloured synthetic bristles are complimented by pale gold-hued ferrules with glossy olive-toned handles, in an olive-toned vegan leather case for storage on-the-go.
