OLIVE YOUNG Fillimilli Eye Smudge Brush is a "specialized eye blending tool" from OLIVE YOUNG’s Fillimilli line, designed to solve the common problem of "harsh eye makeup edges" with its unique shape and soft, flexible hair. Its core features are:

1. Compact, Rounded Brush Head: The brush head is small and rounded (about 0.8-1cm in diameter)—perfect for targeting small eye areas (e.g., upper lash line, lower lash line, outer corner of the eye). The rounded shape ensures even pressure during smudging, avoiding uneven blending or "holes" in the makeup.
2. Soft, Flexible Synthetic Hair: Made with high-quality PBT synthetic hair (polybutylene terephthalate)—softer than traditional nylon hair, with just the right amount of flexibility: it bends with gentle pressure (to hug the eye’s curves) but retains enough structure to control the smudging range (no messy over-blending). The hair is dense enough to hold product but not too dense to trap excess powder.
3. Ergonomic Short Handle: The handle is 10-12cm long (shorter than full-size eye brushes)—designed for "close-up control" when working on small eye areas. It is made of matte ABS plastic, which is non-slip (even with slightly oily hands) and lightweight, reducing hand fatigue during detailed smudging.
4. Multi-Purpose Functionality: While designed for smudging, it works with multiple eye products:
   • Eyeshadow: Softens the edges of dark eyeshadow on the lash line or outer corner, creating a gradient effect.
   • Eyeliner: Smudges pencil or liquid eyeliner (after it sets slightly) to create a soft, "smudged liner" look (instead of a sharp line).
   • Lower Lash Line: Applies and blends light eyeshadow on the lower lash line, avoiding a "heavy" or "stiff" appearance.
5. Durable & Easy to Clean: The thick aluminum alloy ferrule (metal connector) is tightly crimped to the handle and hair, preventing shedding or loosening. The synthetic hair dries quickly after cleaning (usually 4-6 hours), and the brush maintains its shape even after 20+ washes—ideal for long-term use.

（specific ingredients subject to product packaging; common core components listed below）：Key Brush Hair Material:
PBT Synthetic Hair (Polybutylene Terephthalate)—a high-performance fiber tailored for eye smudging: ① Ultra-soft texture (gentle on the delicate eye area, no scratching or irritation); ② Moderate flexibility (bends to fit the eye’s curves for even smudging, but doesn’t collapse under light pressure); ③ Good product retention (holds eyeshadow/liner product enough to blend, but not too much to cause buildup); ④ Hypoallergenic (no animal hair, safe for users with allergies or vegan preferences).
Ferrule (Metal Connector) Material:
Thick Aluminum Alloy—superior for smudge brushes: ① High rigidity (tightly secures the hair to prevent shedding, even with repeated bending); ② Rust-resistant (no corrosion when cleaned with water, ensuring long service life); ③ Lightweight (adds minimal weight to the brush, keeping it easy to control); ④ Smooth edges (no sharp parts to damage the brush hair or irritate the skin).
Handle Material:
Matte ABS Plastic (Acrylonitrile Butadiene Styrene Copolymer)—ideal for eye brush handles: ① Non-slip surface (provides a secure grip, even with sweaty or oily hands during detailed smudging); ② Impact-resistant (does not crack or break easily if dropped, durable for daily use); ③ Lightweight (about 4-5g per handle)—reduces hand fatigue during long smudging sessions; ④ Chemical-resistant (no discoloration or deformation when in contact with makeup products or cleaners).
Auxiliary Material:
Polyester Stitching Thread—used to reinforce the hair-ferrule connection: ① High tensile strength (prevents the hair from pulling loose during repeated use); ② Water-resistant (does not dissolve or fray during cleaning); ③ Colorfast (matches the ferrule color, no fading over time).
Note: All materials comply with international safety standards for cosmetics accessories (e.g., EU REACH, US FDA)—free of toxic substances (e.g., lead, phthalates, latex) and safe for direct contact with the delicate eye area.

Prepare Before Use: Ensure the brush is clean (new brushes may have loose hair—tap gently to remove before first use; clean used brushes every 2-3 weeks to avoid product buildup). Pair it with the target product: powder eyeshadow (matte or shimmer), pencil eyeliner, or cream eyeshadow (ensure cream products are not too wet to avoid clumping).
For Smudging Eyeshadow:
Step 1: Apply your base eyeshadow first (e.g., light color on the lid, medium color on the crease).
Step 2: Dip the rounded brush head into a darker eyeshadow (e.g., brown, gray for smoky eyes)—tap lightly to shake off excess powder (prevents fallout).
Step 3: Focus on the target area (e.g., upper lash line): Hold the brush horizontally, and use gentle, circular motions to smudge the eyeshadow along the lash line. Move slowly outward to blend the color into the base eyeshadow—avoid pressing too hard (which removes the base color).
Step 4: For the lower lash line: Turn the brush vertically, use the tip of the rounded head to apply a small amount of light eyeshadow, then smudge with back-and-forth strokes to soften the line.
For Smudging Eyeliner:
Step 1: Apply pencil or liquid eyeliner along the upper/lower lash line—wait 10-15 seconds (let it set slightly, not fully dry, or it won’t smudge).
Step 2: Use a dry brush head (no product) or dip it in a matching eyeshadow (e.g., black eyeshadow for black liner) for deeper color.
Step 3: Hold the brush gently, and smudge the liner with short, back-and-forth motions—focus on the outer 1/3 of the lash line for a "winged smudge" effect, or smudge the entire line for a soft look.
Blend & Refine: After smudging, check for harsh edges—if any remain, use the clean brush head to lightly sweep over the area to soften further. If there is fallout on the cheeks, use a clean fluffy brush to dust it off.
Clean & Store: After use, store the brush in a makeup brush holder or protective case (avoid pressing the rounded head to prevent flattening). To clean: Mix mild shampoo or brush cleaner with warm water, swirl the brush head in the soapy water (avoid getting water on the ferrule/handle), rinse thoroughly, squeeze out excess water, and lay flat to dry.
Tip for Beginners: Start with a dry brush (or lightly dipped brush) to practice—wet or over-loaded brushes are harder to control. Use gentle pressure—smudging is about "softening," not "removing" color.
