Boao Car Diffuser Bottles 50-Pack — 8ml Glass Cylinders with Wood Caps & Hanging Cords, Refillable Bulk Set

Boao 50-pack empty hanging car diffuser bottles with wood caps, stopper cords, instruction cards and resealable bags—ready to fill with your preferred fragrance for gradual scent release.

These compact glass cylinders pair a natural wood cap with an adjustable hanging string and a tight stopper to create a simple, refillable car air diffuser system. Each bottle holds roughly 8 ml so you can blend or decant essential oils, fragrance blends, or commercial car scents. The packaged set also includes double-sided instruction cards and clear resealable display bags, making the collection useful for small retail, gifting, or bulk personal use.

How do these bottles release scent steadily?

The wood cap acts as an absorbent wick that soaks up oil from the sealed glass bottle and dispenses aroma slowly into the air. The stopper prevents spills while the rope allows secure hanging from mirrors or vents without direct contact. The combination produces a milder, longer-lasting diffusion than an open bottle.

• Natural wood cap absorbs and diffuses fragrance gradually
• Cork-style stopper reduces leakage during transport
• Approx. 8 ml capacity balances runtime and portability
• 20 cm adjustable rope for versatile placement

What comes in the pack and how is it packaged?

You receive 50 glass bottles with wood caps and hanging cords, plus 50 double-sided instruction cards and 50 frosted resealable bags sized for retail-ready presentation. The instruction cards explain filling, care and basic safety, while the bags protect bottles and create a tidy, display-friendly unit. This full set is aimed at sellers, gift makers, and DIYers who need a large, consistent supply.

• 50 clear glass bottles, each ~8 ml
• 50 wooden caps with hanging cord and stopper
• 50 printed instructional cards (9 x 5.4 cm)
• 50 resealable frosted bags with hanging hole (15 x 10.5 cm)

How should I use and care for these car diffusers safely?

Fill the bottle only with non-flammable, manufacturer-appropriate fragrance concentrates and screw the wood cap on firmly. Avoid open flames, high temperatures, and blocking the driver’s sightline; check the wood cap’s ventilation holes periodically. If a spill occurs wipe it immediately and replace any degraded components.

• Do not use flammable or explosive liquids
• Avoid placing near heat sources or direct sunlight
• Inspect vent holes and caps regularly for proper diffusion
• Tighten stopper and cap to minimize leakage when parked
