Most dropper bottles are glass. Most squeeze tubes are imprecise. This package bridges the gap.
The LISSON 19mm PE tube replaces the fragile glass dropper bottle with a lightweight, shatterproof, travel-friendly alternative — while the integrated TPE dropper tip delivers the same pinpoint accuracy as a traditional dropper, but without the separate rubber bulb, without the risk of contamination, and without the mess.
Available in 5ml, 10ml, 15ml, 20ml, and 30ml capacities. One diameter. One closure system. Infinite possibilities.
Quality certifications:
ISO 9001:2015
ISO 22716 (GMP for cosmetics)
FDA-registered facility
REACH compliant
Prop 65 compliant
Tube manufacturing:
Seamless body — no weld lines, no weak points
Uniform wall thickness (±0.05mm) — consistent squeeze pressure across entire tube
Clean shoulder — no sharp transitions where product gets trapped
Neck precision — tolerances within 0.1mm for perfect cap and dropper fit
TPE dropper manufacturing:
Injection-molded TPE — no flash, no burrs, no rough edges
Precision orifice — laser-verified after molding
Permanent bond to PE neck — tested to withstand 10,000+ squeeze cycles
Self-seal validation — each batch tested for drip-free performance
PP cap manufacturing:
Precision threads — smooth engagement, no cross-threading
Consistent torque — removable by hand but secure during shipping
Liner integrity — induction seal bonds cleanly, no residue
Special effects on tube body:
Pearlescent: Subtle shimmer — catches light on shelf
Metallic flake: Bold, high-impact — premium positioning
Color-shift: Changes color based on viewing angle — high-end, collectible
Glow-in-the-dark: Niche applications (nighttime skincare routines)
Color matching guarantee:
LISSON maintains a ΔE < 1.0 tolerance across all production batches — visually indistinguishable from your approved master sample.
