Wood Grain Aluminum Collar with Black Rubber Bulb
This glass dropper combines a wood grain aluminum collar, black rubber bulb, PP plastic inner ring, and transparent glass pipette in one dispensing assembly. The displayed configuration weighs 5g, with the wood grain collar providing its most recognizable exterior detail while retaining the confirmed aluminum collar construction.
- Wood Grain Aluminum Collar: The current version uses an aluminum outer collar with a confirmed wood grain appearance.
- Black Rubber Bulb: The black bulb provides the manual actuation point for drawing and dispensing liquid through the glass pipette.
- PP Plastic Inner Ring: A PP plastic ring forms part of the confirmed dropper assembly.
- Glass Pipette: The transparent pipette can be configured by length, tube diameter, and tip structure according to the packaging project.
- Confirmed Weight: The complete displayed dropper assembly weighs 5g.

21mm Outside Diameter and 82mm Complete Dropper Height
The displayed dropper has a confirmed outside diameter of 21mm, a cap height of 34mm, and a total assembled height of 82mm including the glass pipette. These measurements describe this specific configuration and provide useful reference points for preliminary component and packaging evaluation.

The 21mm measurement refers to the outside diameter of the displayed dropper. It does not identify a bottle neck size or confirmed thread specification. Because the threaded closure is selected according to the bottle neck dimensions, procurement teams should evaluate the actual bottle interface separately from the exterior diameter of the dropper.
Threaded Closure and Bottle Specific Pipette Matching
The closure, glass pipette, and rubber bulb are configured according to the selected bottle. The threaded cap is matched using the bottle neck dimensions, while pipette length and related component specifications can be coordinated around the bottle geometry. No exact thread size or standardized neck finish has been confirmed for the displayed configuration.
- Threaded Closure: The required screw closure configuration is determined according to the actual bottle neck dimensions.
- Pipette Length: Glass pipette length can be customized to coordinate with the selected bottle.
- Tube Diameter: The glass tube diameter can be matched as part of the required pipette specification.
- Pipette Tip Structure: Straight and rounded glass pipette tip structures are confirmed options.
- Bulb Specification: The rubber bulb specification can be coordinated with the bottle and complete dropper configuration.

Wood Grain Appearance and Aluminum Collar Customization
The wood grain aluminum collar distinguishes the displayed version from conventional solid-color metallic dropper collars. For other packaging directions, confirmed aluminum collar customization includes electrochemical coloring, anodizing, glossy, matte, and brushed surface effects. Available collar colors include gold, silver, black, rose gold, and other custom colors.

The rubber bulb can be specified in black, white, and other custom colors. These confirmed options allow buyers to coordinate the visible collar and bulb while separately defining the technical pipette configuration. Optional aluminum colors and surface treatments should be treated as customization choices rather than finishes automatically included with the displayed wood grain version.
Custom Glass Pipette Configuration for Cosmetic Packaging
The glass pipette can be configured around the selected bottle rather than treated as a fixed-length component. Confirmed options include customized pipette length, tube-diameter matching, and straight or rounded tip structures. This is particularly relevant when the same exterior dropper direction is being evaluated across bottles with different dimensions or internal geometry.

FOLOVER PACK supports wholesale and custom glass dropper projects by coordinating the confirmed aluminum collar, rubber bulb, PP plastic inner ring, glass pipette, and bottle-specific threaded closure requirements. Buyers can define the collar appearance, bulb color, pipette length, tube diameter, and tip structure while coordinating the final assembly with the selected bottle.
1000 Piece Standard MOQ and Custom Dropper Order Preparation
The confirmed MOQ is 1,000 pieces for the standard regular-stock item. Customized products should be discussed separately because project requirements may change according to the requested aluminum collar color or surface effect, rubber bulb color, pipette dimensions, tip structure, and bottle-specific closure configuration.
Before placing a customized bulk order, buyers should provide the intended bottle information and define the required component appearance. The assembled sample can then be used to confirm the threaded connection, appropriate glass pipette length and tube configuration, rubber bulb specification, and selected decorative direction. This gives procurement and packaging teams a clearly defined bottle-and-dropper combination for final approval.
