We treat every bag project as a collaboration. Our process is structured but flexible, so we can support you whether you’re a first-time creator or an experienced brand.
1. Initial Consultation
We start by understanding what you’re trying to achieve:

• What is the bag for?
• Who will use it?
• What are your must-have features, budget, and timeline?

You can come to us with a detailed brief or just a rough idea—we’ll help shape it into something workable.
2. Concept Development
Once we’re aligned on direction, our team develops initial concepts.
This might include:

• Sketches or digital renderings
• Moodboards and style references
• Material and colour suggestions

We use this stage to explore options and make sure we’re moving in the right aesthetic and functional direction.
3. Design Refinement & Branding
Here we refine the details that make your bag truly yours:

• Panel layouts and pocket configurations
• Logo placement and branding applications
• Hardware choices (zips, buckles, clips, etc.)

We can offer different branding techniques such as:

• Printing
• Embroidery
• Laser cutting
• Embossing

You choose the method that best matches your brand style and budget.
4. Material Selection
We guide you through selecting the right materials based on:

• Look and feel
• Durability and intended use
• Weight and performance
• Sustainability preferences

You can choose from options such as leather, nylon, polyester, canvas, and eco-friendly alternatives.
5. Prototype Development
We then create a prototype so you can:

• See the design in real life
• Test functionality and comfort
• Review branding, details, and overall construction

This is the point where we fine-tune before committing to bulk production.
6. Final Approval & Production
Once the prototype is approved, we move into production.
Our manufacturing partners and skilled technicians ensure:

• Consistent quality
• Accurate branding
• Reliable construction and finishing

Throughout the process, we keep communication open so you always know where your project stands.

We believe the right materials make a huge difference to performance, longevity, and environmental impact.
Wide Range of Material OptionsWe work with a broad selection of materials to suit different markets and price points, including:

• Leather – classic, durable, ideal for premium and corporate products
• Nylon – strong, lightweight, and great for everyday or performance bags
• Polyester – versatile and cost-effective, with many colour and finish options
• Canvas – robust and casual, suitable for lifestyle and outdoor styles
• Eco materials – recycled fabrics, organic cotton, and lower-impact options for more sustainable collections

Quality & TestingWe source from trusted suppliers and carefully check materials for:

• Durability
• Colourfastness
• Performance under expected use

Responsible SourcingWhere possible, we favour:

• Suppliers with responsible production practices
• Materials with reduced environmental footprint (e.g. recycled or organic content)
• More sustainable approaches to production and packaging

Because we control the design and development process, we can customise your bags at multiple levels:

• Shape, size, and compartments
• Fabric and colour combinations
• Hardware and trims
• Internal organisation (pockets, sleeves, organisers)
• Branding method (print, embroidery, patch, emboss, etc.)

Our goal is to align your product with your brand identity, your customer’s needs, and your commercial targets.
