BBTO Car Diffuser Bottles 100-Pack, 8ml Clear Square Glass with Wood Caps & Cords

These are 100 clear square glass car diffuser bottles with wooden screw caps and strings, each holding about 8 ml for creating portable hanging air fresheners.

BBTO’s bulk set supplies a large quantity of small, refillable glass bottles designed for car aroma diffusers, DIY reed or hanging sachets, and small-sample presentation. Each bottle pairs a transparent square body with a natural wood lid and a cotton or rope hanging cord, offering a compact, attractive vessel for essential oils, fragrance blends, or small decorative fillers. The empty design makes them suitable for crafters, small business owners, event planners, and anyone who wants easy-to-use scent delivery in tight spaces like cars, closets, or bathrooms.

How big are these bottles and what is their capacity?

Each vial is a very small, square-shaped bottle that holds roughly 8 ml (0.28 oz) of liquid. The compact dimensions make them ideal for hanging from rearview mirrors or tucking into tight spots without obstructing views.

• Height: ~1.97 in (5 cm)
• Base footprint: ~1.46 x 1.10 in (3.7 x 2.8 cm)
• String/cord length: ~7.87 in (20 cm) total
• Capacity: ~8 ml (0.28 oz) per bottle

How do you use these empty car diffuser bottles?

Using them is straightforward: remove the plug or inner stopper, pour in your chosen liquid fragrance or essential oil blend, then replace the plug and screw on the wooden cap. Shake gently so the liquid wets the stopper, which lets scent slowly diffuse through the lid and hanging cord.

• Fill directly with fragrance oil, diluted blends, or reed carrier liquid.
• Soak the stopper or allow cap contact for gradual scent release.
• Hang by the cord from a mirror, hook, or inside a small enclosed area.
• Refill and reuse to reduce single-use waste.

Can these bottles be used for projects beyond car fresheners?

Yes — the design is versatile for retail samples, event favors, craft kits, or scent-testing setups. Their clear glass and wood caps offer a simple, neutral aesthetic that complements many DIY and commercial uses.

• Wedding or party favors filled with custom scent or tiny keepsakes.
• Retail sample vials for perfumers and small-batch brands.
• Closet, drawer, or bathroom scent pods.
• Craft projects such as mini terrariums, glitter displays, or message-in-a-bottle gifts.

Who is this for? This 100-piece BBTO pack is suited to anyone who needs many small refillable bottles: car owners who rotate scents, makers selling sample sizes, event planners preparing favors, or craft enthusiasts building custom aroma products. The set’s neutral glass and wood finish keeps presentation simple and professional, while the generous quantity supports repeat use, gifting, or retail sampling without immediate repurchasing.
