The Emissu 7-piece set utilizes a borosilicate glass internal vial protected by an anodized aluminum outer shell. This dual-layer construction is designed to protect delicate liquids—like high-end fragrances or skincare toners—from light-induced degradation while providing a sturdy exterior that resists crushing in a bag.
The use of glass ensures that there is no "scent ghosting" or chemical leaching, maintaining the purity of the contents. The 5ml capacity is specifically optimized for TSA compliance, making it a practical choice for short trips. A small window in the aluminum sleeve allows you to see the remaining volume without having to disassemble the unit.
Practical usability indicates that the fine mist nozzle is rated for over 1,500 uses. However, the seal mechanism relies on correct threading; to prevent evaporation or leaks, ensure the cap is tightened securely but not over-torqued. These bottles are most effective with low-viscosity liquids; thicker "parfum" concentrations or oils may occasionally cause the fine mist nozzle to clog.
For those who need a larger capacity for sanitizers rather than perfume, the Gtile 4-Pack Leather Keychains provide 30ml of storage with a different aesthetic.
When not in travel use, these small atomizers can be neatly stored in felt velvet jewelry drawer compartments to prevent the aluminum shells from scratching each other.
