STRING THEORY Hannah women's pheromone roll-on perfume oil — travel rollerball (3 hr), spicy sweet vanilla amber

STRING THEORY x Off Campus "Hannah" is a travel-size pheromone-mimetic roll-on perfume oil that blends dark rum, vanilla orchid, amber and tonka to create a warm, boozy gourmand scent that lasts about three hours.

Built around the brand's Invisible String Theory and formulated in New York, this compact rollerball uses Phero‑Mimetic™ Technology to interact with your skin chemistry and create a personal scent aura. Hannah layers gourmand sweetness, creamy florals and dry musk for an intimate fragrance that’s easy to carry, reapply, and layer with the full‑strength eau de parfum.

How does Hannah smell and what notes will I notice?

Hannah opens with rich, boozy top notes of dark rum and vanilla orchid, followed by a creamy floral heart and a base of tonka bean and musk. The overall profile is warm, sweet, and slightly spicy — a modern gourmand with an oriental, amber backbone.

• Top: dark rum, vanilla orchid, honeyed sweetness
• Middle: creamy jasmine and amber warmth
• Dry: tonka bean, soft musk, lingering gourmand depth

How long does the roll-on oil last and how strong is it?

This Hannah rollerball is formulated as a lighter, personal-intensity fragrance that typically lasts around three hours on skin. It contains an 18% fragrance concentration—closer to eau de parfum strength—but delivered as an oil roller for intimate diffusion rather than a heavy projection.

• Approximate wear time: 3 hours per application
• Fragrance concentration: 18% eau de parfum equivalent
• Intensity: personal bubble; layer with the full perfume for more presence

How should I apply Hannah for best results?

Apply the roll-on to warm pulse points—wrists, behind ears, base of throat or inner elbows—to activate the scent with your body heat. For longer or stronger effect, layer the roller oil under the matching STRING THEORY eau de parfum or reapply throughout the evening.

• Use on pulse points to concentrate warmth and diffusion
• For more projection: apply oil then spray matching parfum on same points
• Travel-ready size for touch-ups during nights out or special occasions

What is Phero‑Mimetic Technology and how does it change the experience?

Phero‑Mimetic is STRING THEORY’s proprietary approach that aims to mimic pheromone-like effects by responding to your skin chemistry and scent perception. It’s designed to shape the fragrance’s emotional and social impression rather than make specific biological claims.

• Designed to interact with natural skin chemistry for a personalized aroma
• Formulated by lovers in NYC to create intimate, confidence-boosting scent moments
• Non-prescriptive: focuses on scent experience and perceived attraction

Who is this for? Hannah is ideal for people who prefer a warm, gourmand fragrance with intimate projection—those who want a portable, easy-to-reapply scent that reads cozy and seductive rather than loud. Choose this rollerball if you enjoy vanilla‑amber gourmand fragrances with a boozy top, want something travel-friendly, or plan to layer personal oil with a matching perfume for varied intensity.
