Custom-made
Custom glass design: truly unique products for strong brands
Not every brand fits within existing design languages. When design, proportions, or functionality need to be precisely tailored to the product, filling process, and brand identity, KEFLA develops fully customised glass solutions — independently designed, technically validated, and ready for full scale production.
Start enquiryBrand DNA translated into glass
A strong brand follows a clear line. In custom production, the glass bottle isn’t adapted from existing shapes — it is developed consistently from the brand itself. Proportions, shoulder line, base, mouth, and weight are carefully designed, tailored to the intended effect, handling, and market use. The result is not a unique shape for its own sake, but glass packaging with a clear design purpose and a brand-defining presence.
Design freedom with an eye on feasibility
Customisation means freedom — without compromising production. All design decisions are technically evaluated from the start: wall thicknesses, tolerances, mouths, and series processes are considered from the outset. This prevents later adjustments and ensures that design and production remain fully aligned.
Maximum brand impact through distinctiveness
Unique bottles create strong brand recognition and remain memorable. Their originality attracts attention at the point of sale, transforming the bottle into a defining element of the brand and a clear differentitaor in the market.
Four steps to a customised bottle
Idea & consultation
Together, we define the objectives, brand impact, and technical requirements for the new glass bottle. Market positioning, filling process, and economic feasibility are considered from the outset, creating a solid foundation for reliable, targeted development — with a clear focus on stable and cost-effective full scale production.

Design & visualisation
Initial concepts are brought to life. High-quality 3D visualisations and glass-look models let proportions, impact, and tactile feel be experienced early on. At the same time, the design is technically refined and developed into the final glass drawing, ready for series production. Adjustments are made quickly and reliably.

Prototyping & testing
Production tools are built based on the final glass drawing. A sample production run in glass demonstrates under real conditions how the bottle performs during production, filling, and use. The design and technical specifications are then validated.

Series production & quality
With the start of full-scale production, the glass bottle is manufactured under consistently controlled conditions. Inline inspections and statistical quality checks monitor the entire process, ensuring consistently high product quality. On request, KEFLA also supports filling tests to guarantee smooth operation in later use.

"What we appreciate about KEFLA is their proactive approach. Ideas were not simply implemented but questioned and further developed. The result is a bottle that clearly reflects our brand today."

Frequently asked questions
Do you have questions about custom-made products?
We have the answers.
Existing filling processes are assessed early on and actively incorporated into the development. This includes factors such as depalletizing, conveying behaviour, stability, gripper handling, and the requirements of labeling, closing, and packaging systems.
On request, KEFLA also supports filling trials to ensure seamless and reliable integration into existing production lines.
Technical feasibility is addressed from the outset. Factors such as wall thickness, tolerances, finishes, weight distribution, and production processes are integrated early in the design phase. Each concept is thoroughly validated and optimized for manufacturability before approval, ensuring reliable implementation and a clear path to series production.
Once the technical design is finalized, production molds are developed. An initial sample run of around 50 to 100 glass bottles allows for validation under real manufacturing and application conditions. Functionality, handling, and process stability are tested, with targeted refinements made before series production begins.
The investment mainly covers development services and tooling. It is specific to each project and depends on factors such as shape, dimensions, technical design, and planned annual volume. As demand grows, additional production molds are required to achieve the desired output efficiently.
As a general guideline, for a 500 ml bottle with an annual volume of around 50,000 units, development and tooling costs typically range between €10,000 and €20,000.
What matters most is the long-term perspective: a distinctive design strengthens brand identity and pays off over time through scale, product lifecycle, and clear market differentiation.
The economically viable minimum order quantity for a custom bottle depends on factors such as shape, dimensions (height and diameter), weight, finish, glass quality, and compatibility with existing production lines. The objective is always to balance investment, expected volume, and market potential for a sustainable long-term solution. Depending on the product and technical setup, production can be viable from quantities of around 20,000 units.
The development timeline depends on factors such as complexity, coordination requirements, and tooling. In most cases, the process takes around 6 to 9 months—from initial strategy and design through to technical development, sampling, and validation. By integrating design, engineering, and production within the Innovation Camp, decision-making is streamlined and timelines are managed efficiently.
A custom design is the right choice when a brand needs a distinctive visual language that standard solutions can’t fully deliver. This may be driven by strategic goals—such as premium positioning and clear differentiation—or by functional requirements like the filling process, handling, or product protection. The aim is always to create a glass solution that aligns brand identity, performance, and cost efficiency.
An interdisciplinary team of design, engineering, and production experts supports the project through every phase. Development, validation, and series implementation are delivered from a single source, minimizing interfaces and ensuring efficient coordination.
A dedicated main contact guides the client throughout the process, coordinating all internal activities and ensuring clear, transparent, and goal-oriented communication.
