I believe this is an accessory from a Dior cosmetics coffret, probably a limited edition set, from about 10 years ago. There was a white rubber band holding the palette, etc. It seems to have been a set with a cheek brush and lip brush. The pink one is a cheek brush & lip brush, and the silver one is just a cheek brush. They are unused, but there may be some natural deterioration of the brushes. The lip brush is also unused. Since these are used items, please refrain from purchasing if you are looking for new, perfect condition items. Thank you! Size: The cheek brush is a retractable type. 7.5cm when closed, 7.5cm when the brush is extended. Slide type. Lip brush length: 7cm The rubber band seems durable, so it should be fine. These items were found while cleaning out a makeup chest. Selling as a set of two.
