24mm Double-Layer Dropper Cap

Adopts exclusive two-piece double-shell construction for 24mm caliber. The tightly fitted inner and outer shells boost structural firmness, avoiding loose deformation after repeated twisting and disassembly, with more stable overall structure than ordinary single-layer dropper caps.

The layered outline creates prominent visual depth and texture. It upgrades the packaging grade of large-bore essence, concentrated serum and premium skincare liquids, enabling products to gain stronger shelf competitiveness among similar cosmetics.

Supports independent color customization for inner and outer layers. Brands can formulate unique color combinations to build exclusive visual recognition, enrich packaging design details and highlight personalized brand styling.
