Customized 3g Empty Lipstick Tube in Matte Color with MOQ 12000pcs for Premium Lipstick Packaging

Key Components of a Lipstick Tube:

1. Cap: Covers and protects the lipstick bullet. It must fit snugly to prevent the lipstick from drying out or getting damaged.

2. Barrel (or Base): The main outer body of the tube that the user holds. This is often where the brand's logo and color are displayed.

3. Twist Knob (or Swivel Base): The part at the bottom of the barrel that the user twists.

4. Inner Mechanism (Cartridge): This is the heart of the tube. It consists of:

   • Spiral Thread: A helical track inside the barrel.

   • Carrier (or Cup): A small platform that holds the lipstick bullet. It has a "finger" that follows the spiral thread.

   • Seal: Often a small rubber or plastic ring that holds the lipstick bullet snugly in the carrier.

5. Shoulder (or Neck): The top part of the barrel that tapers inward, providing a seal against the cap and a guide for the lipstick as it moves up and down.

6.
