The problem we solve

Most bag factories are not design partners.

Ask a factory for a 600D polyester school bag and you will get a photograph. Ask for the stitch density, the bar-tack spec, the zipper brand, the shade band and the AQL, and the conversation changes.

We publish ours. Every quote comes with a tech pack, a graded size sheet, a costed price band and a lead time we will hold to in writing. That is the whole difference.

01

A design room, not a catalogue

Four designers and six pattern makers. You get a graded size sheet, a stitch map, a bill of materials and a nesting layout — not a photo of somebody else's bag.

02

One roof, not four vendors

Cutting, stitching, branding, foam work and packing all happen in Bahadurgarh. A bag is never split across four suppliers, and never assembled by someone who did not cut it.

03

A price band, not a list price

Costing is built from fabric GSM, hardware, branding process and volume — and shown to you in three tiers before you pick one. The Spec Builder does it live, with no email required.

Capability

What is actually in-house.

Capacity claims are cheap. These are the numbers behind them — and every one of them is auditable on a factory visit or a third-party inspection.

01

Design & Pattern Room

Four industrial designers and six pattern makers. You get a graded size sheet, a tech pack and a nesting layout — not just a photo of a bag someone else made.

14 in-house

02

Eight Production Lines

Lockstitch, overlock, bartack, buttonhole, high-frequency welding and foam lamination. All under one roof in Bahadurgarh, so a bag is never split across four vendors.

8 lines

03

In-House Branding

Six-colour screen printing, 40-head embroidery, heat transfer, badge stamping and label sewing. Setup is done here, which is why a 100-piece run can carry a real woven label.

Capacity That Holds

Two hundred and fifty thousand units a month across four shifts. We quote against a live capacity board, not a theoretical ceiling, so lead times mean something.

The range

Nine silhouettes. Endless specifications.

Every one of these is a starting point, not a fixed product. Fabric, colourway, hardware, lining and branding are all specified by you — and every card below carries the numbers our floor works to.

The Spec Builder

Price a bag before you send an email.

Choose a silhouette, a fabric, a colourway, a branding method and a hardware finish. The builder returns a live spec card, a costed price band at three volumes, your real MOQ and a lead time calculated from the actual production path.

  • Costed from fabric GSM, hardware and branding process — not a guess
  • MOQ recalculated when branding or hardware sets its own minimum
  • Lead time includes the material, not just the stitching
  • Export-ready spec you can hand to another factory if you want a second source

Process

Eight steps. No surprises.

From the first brief to the carton on the dock, this is the order as it actually runs — including the parts most factories leave out of the diagram.

01

Brief & Feasibility

You send a sketch, a reference photo, a tech pack, or a bag you already like. We read it for buildability — not whether we like it, but whether our machines can hold it, and at what cost.

No obligation24-hour acknowledgement1–2 days
02

Specification & Costing

You get a manufacturability review: proposed materials with GSM and denier, a graded size sheet, a costed price band across three volume tiers, and a lead time we will hold to in writing.

Price band, not a list priceWritten lead time2–4 days
03

Pattern & First Sample

Our pattern room grades the design to your size chart, nests the panels in CAD and cuts a first sample. This round proves structure, proportion and hand-feel. Expect it to be approximately right.

CAD nestedPhoto + video record7–10 days
04

Revisions & Golden Sample

Two refinement rounds are included. When you sign the golden sample in writing, that physical bag becomes the production standard — every measurement, seam placement and colour is matched against it on the floor.
