Handbag Tech Pack: What to Prepare Before Sampling

Quick answer: gather the decisions the sample maker must not guess

A useful Tech Pack records the product reference, dimensions, materials, components, construction notes and open decisions in one controllable version. It does not need to be perfect before discussion, but it must make assumptions visible.

A handbag idea becomes much easier to discuss when the important details are not hiding in a mood board, a voice note and three separate message threads. That is what a tech pack—or a simpler early sample brief—is for.

You do not need a perfect formal document before speaking with a manufacturer. You do need a clear enough record that both sides can see what the bag is meant to do, what cannot change, and which decisions still need discussion. This guide helps you prepare that first working version.

Begin with the bag’s job

Write a short sentence about the person using the bag and the job it needs to do. What should it carry? When will it be used? Does easy access matter more than a clean exterior? Is the product intended to sit on the shoulder, across the body, in the hand or inside another bag?

This context gives the rest of the brief a purpose. It helps you decide which features are essential and gives a supplier a reason to ask better questions about the opening, strap, pockets or structure.

Put the product overview in one place

A first brief can be a marked-up image set, a sketch, an existing sample and clear notes. It does not need to look like an engineering drawing. Try to bring together:

• a project name or style reference;
• front, back, side and interior images where available;
• the intended use and the product details that matter most;
• overall length, height and depth as targets or confirmed dimensions;
• opening, closure, straps, handles, pockets and dividers;
• material, colour and visible-finish references;
• branding, label and packaging notes; and
• a separate list of questions that are still open.

Mark a choice as fixed only when it really is fixed. Mark it as open for discussion when you need feedback. That small distinction prevents an early idea from being mistaken for a final instruction.

Make measurements understandable

Numbers are only useful when people know what they refer to. Start with overall length, height and depth. Then mark any measurement that affects real use: handle drop, strap range, gusset depth, pocket opening, flap overlap or the space needed for a particular item.

Put the measurement point on an image or drawing whenever you can. If the number is still a target, say so. A sample can help you decide whether a target feels right in the hand or on the body; the approved version should then record the points that need to be repeated.

Describe the inside, not only the front view

Many sample misunderstandings begin because the exterior was discussed in detail and the inside was not. Add the lining direction, pockets, dividers, zip compartments, label position and any item the bag must accommodate.

Also describe access. Can the user reach the main compartment easily? Does a pocket need to be secure, quick to reach or sized for a particular object? These questions help you assess the product as a user would, before an interior detail becomes expensive to change.

For a broader material discussion before finalizing the interior specification, see our handbag materials guide.

Show how the bag opens and closes

Write down the opening and closure you want, then explain what it needs to achieve. A closure might primarily protect the contents, create a clean visual line, make one-handed access possible or simply complete the design. A reference image helps, but add a note about the use case beside it.

Include the visible closure, the opening path and any point where it meets a flap, strap, gusset or interior divider. If you have not chosen the final component, describe the requirement and leave the component choice open for discussion.

Give colours and components a controlling reference

For each visible material, hardware item or branded detail, show the clearest reference you have and say where it belongs on the bag. A close-up, swatch, approved sample, marked drawing or written note can be more useful than a general product photo.

Use one record to identify the component, the reference, its location and the current version. If a decision changes after a sample review, update that record. This is less about creating paperwork and more about making sure everyone is talking about the same version.

Do not leave presentation and packing to the final message

Some projects need labels, hangtags, dust protection, stuffing, wraps, carton marks or other presentation details. If any of these matter, place them in the brief or make a linked packing reference with a named owner and version.

You do not need to prescribe a universal packing method. You do need to make your project’s expectations visible early enough to review them against the approved sample and final product reference.

Our handbag packaging preparation guide helps you organise that later-stage reference without turning it into customs or shipping advice.

Use sample feedback as a controlled update

When reviewing a sample, name the part, mark the change and explain why it matters. “Please make this better” gives nobody a stable decision. “Review the strap position against this marked image because the bag must sit higher on the shoulder” gives the conversation a useful starting point.

Keep the date or version beside every revision. Then update the related measurement, component, colour or packing note at the same time. This turns sample feedback into a clearer next version instead of a collection of disconnected comments.

Read our guide to managing handbag sample changes when you are ready to record revisions, and our sample approval guide before you treat a version as the reference for production.

A practical pre-sampling checklist

• Can another person understand the bag’s use and the product direction?
• Are the overall dimensions and the measurements that affect use marked clearly?
• Have you shown the interior, access, pockets and dividers?
• Is the opening and closure explained by both image and use requirement?
• Does every visible material, component and branded detail have a reference and location note?
• Are confirmed decisions separated from questions that remain open?
• Have presentation and packing details been recorded when they affect the project?
• Can every change be tied to a version, image or written reference?

Use the brief to make the next conversation useful

A good brief does not eliminate every question. It makes the right questions visible before assumptions become part of a sample.
