Multi-Cartridge Replaceability: The packaging system holds two (le DUO), three (Airless Shuttle), or four (Airless Shuttle 4S) distinct formulas in one master container, allowing consumers to easily swap out and replace individual empty cartridges. 

Segmented Dispensing: The inner cartridges are shaped as geometric wedges (halves, thirds, or quarters) that fit together to form a cylinder, each equipped with its own independent pump nozzle under a shared transparent cap.

Transparent Casing: A clear outer shell encapsulates the system, allowing the distinct colors of the inner refill cartridges to remain fully visible for easy product identification.

Premium Metallic Accents: An elegant metallic collar, featured in finishes like silver and rose gold, divides the upper dispensing mechanics from the lower cartridge housing.

Personalized Functionality: This modular design allows brands to offer complete, personalized skincare regimens (such as day/night creams or multi-step serums) in a single, refillable unit.

Airless Technology: The collection is built on refillable EBM Airless (bag-in-bottle), which protects sensitive formulas while promoting the reuse of the exterior packaging.

Cartridge Materials: The EBM (Extrusion blow molding) Bag-in-bottle Airless Cartridges can be made in 

• PP exterior wall + PP pouch w/2% EVOH (Recyclable)

• PE exterior wall + PE pouch w/2% EVOH (Recyclable)
