KOBAYASHI Room Diffuser Black 70ml is a flameless, smokeless home fragrance product designed to create a comfortable, fragrant living environment with a sleek black aesthetic. Its core features are:

1. Flameless & Smokeless Safety: Relies on absorbent fiber rods to draw fragrance oil from the bottle and release aroma naturally— no open flames, no smoke, and no risk of overheating, making it safe for use in bedrooms (even overnight), children’s rooms, or near curtains/furniture.
2. Long-Lasting Fragrance: The 70ml fragrance oil provides continuous aroma for 30-60 days (varies by fragrance type and room ventilation)— the slow, steady volatilization ensures the fragrance is not overpowering (subtle enough for daily use) and avoids frequent refills.
3. Sleek Black Design: Features a matte black glass bottle (or plastic bottle with black finish) and matching black fiber rods— the minimalist, monochrome design complements modern, industrial, or dark-themed home decor, avoiding the "overly decorative" look of colorful diffusers.
4. Multiple Fragrance Options: Typically available in classic, versatile scents (e.g., lavender, citrus, jasmine, sandalwood)— lavender for relaxation (ideal for bedrooms), citrus for freshness (great for entryways/bathrooms), and sandalwood for warmth (suitable for living rooms).
5. Easy to Use & Maintain: No assembly or technical setup required— simply insert the fiber rods into the fragrance oil bottle and place it in a well-ventilated (but not windy) area. Maintenance is limited to replacing the entire unit once the oil is used up (no messy refilling of oil).

（specific ingredients subject to product packaging; core components listed below）：
Fragrance Oil (Core Aroma Component):
Natural Fragrance Extracts: Derived from plants (e.g., lavender oil from lavender flowers, citrus oil from orange/lemon peels, jasmine extract from jasmine flowers)— provide a fresh, natural aroma and reduce the risk of irritation compared to synthetic fragrances.
Synthetic Fragrances (Minor Proportion): High-quality, safe synthetic fragrances (e.g., sandalwood-like, vanilla-like scents) used to enhance aroma stability and longevity (natural fragrances may fade faster). These synthetic fragrances comply with international safety standards (e.g., IFRA) and contain no harmful volatile organic compounds (VOCs) like formaldehyde or benzene.
Solvent (Ethanol/Glycerin): A safe, low-irritation solvent (usually food-grade ethanol or glycerin) that dilutes the fragrance oil to ensure smooth absorption by the fiber rods and steady volatilization— avoids overly concentrated aroma or rapid oil depletion.
Diffuser Bottle Material:
Matte Black Glass/Plastic: High-quality, non-toxic glass (or BPA-free plastic) with a black matte finish— glass is more stable (resists chemical reactions with fragrance oil), while plastic is lighter and less breakable. The black finish is achieved via non-toxic coating (no lead or heavy metals).
Fiber Rods (Aroma Absorption & Diffusion Component):
Natural/Synthetic Fiber Blend: Typically made of a blend of cotton, linen, or polyester fibers— the fibers have a porous structure that efficiently absorbs and releases fragrance oil. They are non-toxic, odorless (no extra scent to interfere with the fragrance), and resistant to mold (even when wet with oil).
Safety Assurance:
Free of harmful substances such as formaldehyde, benzene, heavy metals (lead, mercury), and phthalates— tested for skin irritation (even if the oil accidentally touches the skin) and respiratory safety (no harmful fumes when volatilized).
Note: Keep the product out of reach of infants and pets— while the oil is non-toxic, ingestion in large quantities may cause discomfort.

Unpack the product: Remove the diffuser bottle (with sealed fragrance oil inside) and the fiber rods from the packaging. Check that the bottle is intact (no leaks) and the rods are clean (no dust).
Prepare the diffuser: Unscrew the cap of the fragrance oil bottle (some caps have a plastic seal underneath— peel off the seal first to allow the rods to absorb oil).
Insert the fiber rods: Take the fiber rods (usually 3-5 rods included) and insert them vertically into the bottle— ensure the bottom of the rods is fully submerged in the fragrance oil (this allows the oil to be drawn up through the rods). Do not force the rods (they should fit easily into the bottle’s opening).
Choose a placement: Place the diffuser in a well-ventilated area (e.g., a shelf, desk, or countertop) away from direct sunlight, heat sources (e.g., air conditioners, heaters), and strong winds (wind will speed up oil volatilization and reduce usage time). Avoid placing it near food, cosmetics, or fabrics that may absorb the fragrance (e.g., silk, wool).
Wait for aroma release: The fiber rods need 1-2 hours to fully absorb the oil and start releasing the fragrance— the aroma will gradually become stronger and more consistent after 24 hours.
Replace when empty: When the fragrance oil is completely used up (the bottle is empty and the rods feel dry), discard the entire unit (do not refill with other oils, as this may affect aroma quality or cause leaks).
