Explore our highly certified glass container selections featuring precision caps and leak-proof assemblies.
In the modern premium packaging landscape, the transition to custom glass bottles with caps is propelled by two major global forces: chemical inertness and ecological sustainability. As strict directives restrict single-use plastics, global conglomerates in cosmetics, pharmaceuticals, food, and high-end beverages are adopting premium glass vessels. Glass preserves internal formulations without chemical migration, maintaining active ingredients for up to three years.
However, sourcing high-grade glass container components is complex. Global brands require precise tolerances, leak-free closures, and high-speed filling compatibility. This demand has transformed custom glass packaging from simple storage into a complex field of materials science, structural design, and strict quality control.
Why modern global corporations rely on specialized manufacturing hubs to execute complex customized glass container runs with minimal margin of error.
Utilizing high-precision CNC toolings and CAD/CAM software to materialize unique custom shapes, tailored embossed logos, and specialized neck designs that distinguish brands on crowded retail shelves.
Offering secondary processing: inner-lacquering, soft-touch frosting, physical vapor deposition (PVD) metallization, silk-screen printing, and multi-color hot foil stamping for premium cosmetics.
Every batch undergoes strict automated inspection testing for thermal shock durability, mechanical vertical resistance, internal pressure endurance, and cap closure torque compliance.
Lecos Glass has been dedicated to the glass packaging industry for over 10 years, offering innovative wholesale glass bottles and jars for cosmetics, perfume, personal care, essential oils, and candle jar packaging. We pride ourselves on delivering bespoke glass bottles tailored to our clients' precise needs.

Our company is built on a solid foundation of deeply held values that guide our actions and corporate culture. We prioritize social responsibility, ethical standards, and universal human rights.
We are dedicated to protecting the environment and supporting the communities where we operate. By fostering creativity, embracing diversity, and maintaining respectful labor standards, we ensure our production lines reflect the values of the global brands we serve.
Our design focus targets weight reduction in glass containers and the incorporation of Post-Consumer Recycled (PCR) glass. This reduces carbon emissions during melting while maintaining the premium clarity and strength expected by luxury markets.
Analyzing the specific performance parameters, compatibility rules, and localized requirements for custom cap-and-bottle integrations.
High-potency skincare formulas with active ingredients like Vitamin C, Retinol, and Hyaluronic Acid require light protection and chemical resistance. We customize amber, cobalt blue, and solid black dropper assemblies with chemically inert silicone bulbs and specialized caps to prevent oxidation.
Modern luxury relies on weight, feel, and environmental responsibility. We supply heavy-walled cosmetic jars featuring inner refillable cups and customized aluminum or post-consumer resin (PCR) caps. This offers consumers a premium experience while reducing plastic consumption.
Essential oils can degrade plastics and compromise seals. Our Boston Round bottles and custom vials are paired with phenolic caps or polycone liners, ensuring airtight seals that prevent volatile organic compounds (VOCs) from evaporating.

Witness the specialized manufacturing facilities where raw glass batch components are formed, treated, and processed into high-quality glass jars and bottles.
In-depth structural, logistical, and technical insights curated by our quality assurance engineering teams to help you optimize your packaging decisions.
Our pricing model depends on several variables: total run size (order volume), material selection (e.g., flint glass vs. high-flint cosmetic grade), cap specifications (e.g., standard PP plastic, aluminum overcaps, double-walled PCR closures), and customization techniques (frosting, screen printing, inner-lacquering, hot stamping).
We provide detailed pricing estimates within 24 to 48 hours after receiving your design parameters. These estimates include raw unit cost, decoration cost, and packing specifications. To receive a detailed quotation, please contact our team with your custom specifications.
Yes, we require all international orders to have an ongoing minimum order quantity. For standard bottles and jars that we run regularly, the MOQ starts at 10,000 units. For custom mold shapes that require structural tooling, the minimum quantity starts at 20,000 to 30,000 units.
For small brands or test runs, please contact our sales team to check our current inventory and explore options for utilizing existing molds to lower the entry barrier.
Yes, we can provide most documentation including Certificates of Analysis / Conformance, US FDA DMF, EU REACH compliance, heavy metal test reports, and required export/import documents.
Our quality control processes ensure that all glass containers and closure liners are safe for cosmetics, skin care formulas, and pharmaceutical ingredients.
For custom samples, the lead time is about 7 to 10 days if using stock shapes, and 20 to 25 days if custom molds are required. Mass production runs average 20-30 days after receipt of deposit and final approval of pre-production samples.
Lead times become effective when we receive your initial deposit and final approval of the technical drawings. We work with clients to coordinate production timelines with product launches.
You can make payments via bank wire transfer (T/T), Western Union, or PayPal.
Our standard payment terms are a 30% deposit in advance to initiate production, and the remaining 70% balance paid against the copy of the Bill of Lading (B/L) or prior to dispatch, depending on terms agreed upon during contract setup.
We warranty our materials and workmanship. In accordance with ISO 9001 and AQL quality standards, we implement automated optical inspection systems on the cold end of our furnaces to identify cosmetic and structural defects.
If any manufacturing defects exceed the agreed Acceptable Quality Limit (AQL), we will supply replacement vessels or issue a credit. It is our company policy to address and resolve all customer issues to your satisfaction.
Yes, we use high-strength, double-wall corrugated boxes with custom grid dividers and thick plastic wrap to prevent glass friction and breakage during transit. For fragile components like glass droppers, we package them in vacuum-formed trays.
For international ocean freight, all cargo is loaded onto sturdy pallets and shrink-wrapped for stability. We also accommodate custom packing requirements upon request.
Shipping costs depend on the delivery method, shipment weight, dimensions, and port of destination. Express courier is fastest but most expensive, suitable for pre-production samples. Ocean freight is the standard, cost-effective solution for volume orders.
We work with shipping companies to coordinate EXW, FOB, CIF, or DDP shipments. Contact us with your destination address and estimated volume to receive a freight quote.
