• The BIKEN Setouchi Lemon Reed Diffuser is a classic flameless fragrance product launched by the brand based on the natural characteristics of Japan’s Setouchi Inland Sea area. It takes "natural lemon aroma, minimalist Japanese design, and safe long-lasting volatilization" as its core features, and focuses on "soothing the body and mind with natural fragrance and restoring the true freshness of life". Its core advantages are concentrated in three points:
  1. Setouchi Lemon scent, natural restoration without industrial feeling: The fragrance stock solution adopts "real lemon extraction + scientific fragrance blending" technology. The top note releases the fresh aroma of fresh lemon peel (with a slight herbal feeling), neutralizing the cloyingness of pure fruity fragrance; the middle note incorporates the soft sweetness and sourness of lemon pulp, paired with a small amount of lime and bergamot extract scents to enrich the fragrance layers; the base note is based on a light white musk to extend the fragrance retention time (the fragrance can remain stable for 6-8 hours in a 10-15㎡ space). The overall scent is fresh and non-pungent, without the rigidity of chemical fragrances, and fits the olfactory preferences of most people;
  2. Minimalist Japanese design, suitable for multi-style homes: The diffuser bottle is made of transparent or light cyan glass (simulating the clear texture of the Setouchi Inland Sea), with no complicated decorations on the bottle body, only embellished with a simple brand logo or lemon pattern; paired with natural light brown reed sticks, it is fresh and elegant visually, and can be integrated into various home styles such as Japanese minimalism, Nordic style, and modern minimalism. It is not only a fragrance product but also a small decoration that enhances the texture of the space;
  3. Safe and long-lasting, no manual intervention required: Each bottle contains 100ml of fragrance stock solution, paired with 6-8 natural reed sticks (strong adsorption and uniform volatilization). It volatilizes naturally through the siphon principle of the reed sticks, no ignition, power supply, or pressing required. It can be used by unpacking and inserting the reed sticks; in a well-ventilated space, a single bottle can volatilize stably for 4-5 months without frequent replacement; and the stock solution has passed Japan’s strict safety tests, free of formaldehyde, benzene and other harmful substances, so pregnant women and people with sensitive skin can also use it with confidence.

Setouchi Lemon Fragrance Complex: Contains fresh lemon extract (core raw material, possibly from Japan’s Setouchi Inland Sea area, with natural limonene, citric acid and other aromatic components to restore the real lemon aroma), lime extract scent (enhances freshness and neutralizes cloyingness), bergamot essential oil (adds the fresh herbal feeling unique to citrus, enriching layers), white musk mimic scent (as the base note, extends fragrance retention time without sensitization risk); the fragrance concentration is controlled at 0.9%-1.3%, complying with Japan’s "Home Fragrance Safety Standards", free of synthetic musk, phthalates and other harmful substances;
Solvent: Uses food-grade dipropylene glycol, which is highly safe, can efficiently dissolve various components in the fragrance complex, and promote uniform volatilization of the fragrance, avoiding stratification or caking of the stock solution, and has no irritating odor and will not interfere with the purity of the lemon scent;
Stabilizer: Adds hexylene glycol to slow down the oxidation rate of fragrance components, ensuring stable scent without change during the 4-5 month volatilization period (avoiding "sour spoilage" in the later stage); at the same time, it has a mild bacteriostatic effect to prevent the growth of microorganisms in the stock solution during long-term use and ensure safe use.

1. Unpacking Preparation: Open the product packaging, take out the diffuser bottle (with fragrance stock solution) and independently packaged reed sticks, and check if there is any liquid leakage from the diffuser bottle (if there is leakage, gently wipe the bottle body and mouth with a clean paper towel to avoid contaminating the tabletop or hands);
2. Inserting Reed Sticks: Take the reed sticks out of the packaging, hold the middle of the reed sticks with both hands, and insert them vertically into the fragrance stock solution in the diffuser bottle—ensure that the bottom of all reed sticks is completely soaked in the stock solution (no need to insert completely, leave 1/3 of the length outside the bottle mouth) to absorb the stock solution through the siphon principle;
3. Standing and Initial Volatilization: After inserting the reed sticks, do not move the diffuser immediately, let it stand for 10-15 minutes to allow the reed sticks to fully absorb the fragrance stock solution; for the first use, it takes 2-3 hours for the fragrance to fully volatilize through the reed sticks and spread to the entire space (the larger the space, the longer the diffusion time);
4. Placement and Fragrance Adjustment: Place the diffuser in a stable, ventilated position away from heat sources (such as air conditioner vents, radiators, desk lamps), avoiding direct sunlight (to prevent accelerated volatilization of the stock solution); if you want to enhance the fragrance concentration, you can pull out the reed sticks and insert them upside down every 3-5 days (soak the end originally exposed to the air in the stock solution); if you want to reduce the concentration, reduce the number of inserted reed sticks (it is recommended to keep more than 4 sticks to ensure basic volatilization effect);
5. Replacement and Maintenance: When the fragrance stock solution is basically volatilized (the stock solution in the bottle is significantly reduced, the reed sticks become dry, and there is no obvious fragrance in the space), directly replace it with a new diffuser (this product is designed for one-time use, and it is not recommended to add other fragrance stock solutions by yourself to avoid damaging the original scent or causing safety issues); for daily cleaning, just wipe the outer wall of the bottle body with a dry paper towel—do not rinse the inside of the bottle with water.
