Abstract: A device for diffusion of a liquid product, of the perfume type, stored in a reservoir includes at least one fixed part capable of being mounted on the reservoir, and offering at least one point of product supply by capillarity, the fixed part including a fixed porous body capable of being impregnated with product by capillarity by being directly immersed in the reservoir. The device also includes a nomadic element for each supply point, including a mobile porous body capable of being impregnated with product by capillarity while being in contact with the fixed porous body when the nomadic element is mounted on the fixed part. The nomadic element also includes a decorative structure of the jewel type, the mobile porous body being housed inside the decorative structure.

Abstract: A device for three-dimensionally printing a sleeve (10) for receiving a cosmetic applicator (20) is disclosed. The device includes a printer for printing in three dimensions. The printer is designed to receive a digital file and to print the sleeve. The device further includes a calculator capable of adapting the dimensions of the sleeve (10) to be printed to those of a user's finger.
