BBTO 100-Piece 8ml Square Glass Car Diffuser Bottles with Wood Caps - Clear, Refillable Set for Auto & Small Spaces

These are 100 empty 8 ml square glass car diffuser bottles with wooden screw caps and hanging cords, ready for your favorite essential oil blends.

If you make car fresheners, sample scents, or need small refillable vessels for gifts and events, this bulk set gives you a dependable, low-cost supply. Each mini bottle is clear glass with a natural wood lid and string, built to diffuse fragrance passively when filled and hung in a vehicle, closet, or small room. The compact format keeps a long-lasting scent reservoir while remaining unobtrusive in tight spaces.

How do I use these diffusers for best scent release?

Prepare each bottle by removing the inner plug, pouring in 8 ml of your chosen fragrance or essential-oil mixture, then reassemble and hang. The wooden cap and absorbent plug allow fragrance to wick out slowly, producing a steady scent without spills. For stronger aroma, refresh the liquid every few days or use higher-concentration blends.

• Remove plug, pour up to 8 ml (0.28 oz) of oil or perfume.
• Reinstall cap and shake gently to saturate the plug.
• Hang by the attached 20 cm cord in car, closet, or bathroom.
• Top up or replace liquid as scent fades.

What are the size and material details I should expect?

Each diffuser is crafted from clear glass with a natural wood screw cap and a cotton-like hanging cord. Dimensions are compact: roughly 5 cm tall, a 3.7 x 2.8 cm rectangular base, and an 8 ml internal capacity—small enough for tight spaces yet large enough for repeated use. The materials are selected for durability and a minimalist aesthetic.

• Glass body for chemical resistance and clarity.
• Wooden cap for a natural look and controlled wick contact.
• Approximate bottle height 1.97 inches (5 cm).
• String length ~7.87 inches (20 cm) for easy hanging.

Can these bottles be used outside the car, and are they refillable?

Yes — their design is versatile for multiple small-space fragrance needs. They work well in closets, bathrooms, drawers, or as event favors. The glass bodies are refillable and simple to maintain; rinse and dry before switching scent types to avoid cross-contamination.

• Safe for closets, offices, bathrooms, and small rooms.
• Refillable glass makes scent swapping economical.
• Rinse with mild soap to clean between fragrances.
• Great option for DIY branded or handmade gifts.

Who is this for? Makers, small-batch sellers, event planners, and anyone who prefers customizing fragrances will find this 100-piece BBTO set useful. It supplies enough containers for retail prototypes, party favors, promotional giveaways, or to keep multiple scent options on hand. If you need a neutral, attractive vessel that’s simple to fill, hang, and refresh, this bulk pack offers a practical, low-cost solution.
