Boao Hanging Car Diffuser Bottles 50-Set — Black Square Instruction Cards, Wooden-Top & Adjustable Cord

Boao 50Set Hanging Car Freshener Diffuser Bottle with black square instruction cards is a ready-to-use kit of 50 empty wooden-top hanging bottles and double-sided guide cards for creating custom car air fresheners.

This bulk kit provides everything needed to make, label, and hang personalized scent diffusers in vehicles, rideshares, gift packages, or retail displays. Each bottle includes a wooden cap that absorbs and slowly disperses fragrance, an adjustable hanging cord, and a stopper to prevent spills. The matched black square instruction cards (2 × 3.54 inches) are printed on both sides with clear, minimalist directions so recipients can fill and use their diffusers quickly and safely.

How do these hanging diffuser bottles work in everyday car use?

Each bottle is designed to hold a small amount of fragrance or essential oil and release scent through the wooden lid for gradual diffusion. The stopper keeps contents secure during pouring or transport, and the cord lets you suspend the bottle from a mirror or vent without blocking vision.

• Wooden cap absorbs and slowly emits scent for steady fragrance.
• Stopper prevents leaks while filling and during transit.
• Adjustable hanging string fits most rearview mirrors and hooks.
• Compact bottle size conserves perfume or oil for longer use.

What comes in the 50-set, and how are the cards formatted?

The pack includes 50 empty hanging diffuser bottles and 50 black square instruction cards. The cards are double-sided with concise steps and visual cues to make filling, sealing, and hanging straightforward for customers or gift recipients.

• 50 wooden-lid hanging bottles with cords and stoppers.
• 50 double-sided black square instruction cards (2 × 3.54 inches).
• Minimalist design on cards for easy reading and neat presentation.
• Set packaged to supply multiple vehicles, events, or product orders.

How can I personalize these diffusers safely and attractively?

Fill each bottle with your preferred fragrance, essential oil blend, or a premixed air freshener solution. Use the stopper while filling to control flow; insert the wooden cap to begin diffusion. Pair with packaging or labels to create branded gifts or retail items.

• Use fragrance oils at manufacturer-recommended dilution levels.
• Add a small decorative tag or sticker to the cord for branding.
• Include the instruction card inside gift packaging for guidance.
• Replace wooden cap when saturated to refresh scent performance.

Who is this product for? This Boao 50-set is aimed at small businesses, event planners, car-detail shops, ride-share drivers, gift basket creators, and DIY makers who need a consistent, easy-to-use supply of hanging car diffusers. It’s especially useful when you want a uniform presentation—black square cards and matching black cords give a professional, minimalist look—while allowing customers or recipients to choose their own scents. The kit works equally well for personal bulk use when you want multiple vehicles or spaces scented, or for sellers who want a ready-to-sell blank product to customize with labels or scents.
