Boao Hanging Car Diffuser Bottles 50-Set — 8 ml Glass Cylinders with Wooden Stoppers and Adjustable Cords

Boao 50 Sets Hanging Car Diffuser Bottles are refillable 8 ml glass cylinders with wooden stoppers and adjustable cords, sold in bulk with instruction cards and resealable bags for easy car-fragrance setup.

These compact glass hanging diffusers are made for business owners, crafters and anyone who wants a tidy, customizable car scent solution. Each bottle holds about 8 ml and uses a porous wooden cap that releases fragrance slowly when soaked, while the included cords let you hang them from a rearview mirror or other interior anchor. The kit provides 50 complete packs—glass bottle, instructional card and a frosted resealable bag—so you can stock up, distribute samples or bundle them with your handmade aroma blends.

How do I prepare and fill these hanging car diffuser bottles?

Filling is straightforward and requires only your chosen fragrance oil plus the supplied stopper and cord. Remove the wooden cap, pour or pipette in up to the 8 ml capacity (avoid overfilling), replace the cap so the wood soaks up scent, then tie or adjust the hanging string to the desired length before placing in the vehicle.

• Capacity: approx. 8 ml per bottle for concentrated or diluted fragrance oils.
• Stopper: wooden cap absorbs and diffuses scent slowly.
• String length: about 20 cm (7.87 inches) adjustable for hanging height.
• Packaging: each bottle comes with a double-sided instruction card and a 15 x 10.5 cm resealable polyester bag.

What safety and usage precautions should I follow for car use?

These diffusers are designed for passive scent diffusion—not for flammable liquids or open flames. Keep bottles away from direct sunlight and hot surfaces, do not place in areas that obstruct the driver’s view, and check the wooden cap’s vent holes regularly to ensure even diffusion and prevent leaks.

• Avoid filling with highly flammable or volatile solvents.
• Do not use open flames or place near heaters; avoid high-temperature storage.
• Inspect vents and seals periodically for leakage or clogging.
• Maintain clear sightlines—hang where the driver’s view is not blocked.

How can businesses and crafters use this 50-set kit effectively?

The bulk pack suits small retailers, subscription-box curators, event swag, or makers creating private-label car fresheners. With 50 bottles and matching bags and cards, you can brand inserts, pre-fill with signature fragrances, or sell them as sample packs with minimal additional packaging.

• Retail-ready: frosted resealable bags include a hanging hole for display.
• Branding: instruction cards are double-sided and ready for custom stickers or printing.
• Scalable: ample supply for promotions, wholesale or craft fairs.
• Versatile: fill with essential oil blends, commercial car scents, or unscented base for customers to customize.
