Core Cartridge Design: The SRA-ACB refills consist of minimalist, off-white cylindrical bodies with simple white caps, available in three progressively sized height variations.

• SRA-ACB - The Classic Cylinder: The first outer bottle option is a thick-walled, straight-sided transparent cylinder that cleanly encases the white cartridge, topped with a flush white pump assembly.
• SRA-ACF - The Contoured Silhouette: The second exterior style features a transparent shell with elegantly curved, tapered walls, giving the bottle a distinctive hourglass profile.
• SRA-ASA - The Geometric Square: The third option offers a modern, sharp-edged transparent square casing, distinguished by a flat top with a silver metallic dispensing button.

Suspended Visual Effect: Across all three outer bottle styles, the opaque white inner cartridge remains visible through the thick, clear outer casing, creating a premium "floating" aesthetic.

Airless Technology: The collection is built on refillable EBM airless functionality, which protects sensitive formulas while promoting the reuse of the exterior packaging.

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