What should I approve before bulk production begins?
Approve an identified sample and specification covering dimensions, materials, application, connections, finish, logo and packaging. Record review conditions, accepted details and unresolved revisions. Agree which checks cover every unit and which require selected samples or separate tests.
| Review item | What to record | Decision before approval |
|---|---|---|
| Identity and dimensions | Product code, drawing version, material specification and measurement points. | Confirm the selected construction and any open dimensions. |
| Application | Formula, motion, amount and observations about pickup, placement and blending. | Agree which result is acceptable for the intended use. |
| Connections and finish | Alignment, gaps, loose fibres, colour and logo placement. | Define acceptance criteria and any separately specified strength or wear test. |
| Care and shape | Agreed care procedure and the observed condition afterwards. | Resolve changes in shape, fibre condition, finish or assembly. |
| Set and packaging | Contents, protective inserts, labels and packed sample. | Approve the complete configuration rather than the brush alone. |
Identify the sample being approved.
Give the sample a code and retain the associated drawing, finish reference, logo artwork and packaging version. Record proposed changes separately from accepted details. If a revised sample is needed, identify which version supersedes the previous one; a conversation such as “make it softer” is not a complete production instruction.
Use the intended formula and a repeatable review.
For a foundation brush, record the formula and examine placement, blending and remaining brush marks. For a powder brush, examine pickup, release and build-up. Define the application motion and review conditions so two samples can be compared fairly. This checklist proposes a review method; it does not report PRETTY test results.
Connect sample approval to the production process.
PRETTY’s process page sets out 28 recorded production steps, including head-shape and dimension checks, finishing inspections, full inspection and sampling inspection. Those stages show where checks fit into production. A stage name does not specify a pull force, a test cycle count or an acceptance limit: agree the method and criteria for your order.
Distinguish full inspection from a test on selected units.
Confirm which visible or measurable characteristics are checked on every brush and which tests use selected units. A strength or wear test may require a separate method and may be destructive. Ask how defects are recorded, what happens to nonconforming units and when a revised sample or corrective action is required.
Approve the packed product and keep the record.
Review the complete set contents, logo orientation, head protection and packaging with a physical sample. Record accepted details, requested revisions and unresolved items in one approval note. Production scope, quantities and timing should refer to that agreed version; an attractive sample photograph alone is not approval of every specification.
Use this in your sample review
Turn feedback into a revision the factory can act on
The examples below show how to write a review. They are proposed recording methods, not claims that PRETTY has passed a particular test or uses universal acceptance limits.
Swipe across the table to read all three columns.
| Initial feedback | A useful review instruction | Evidence to retain |
|---|---|---|
| “It leaves lines.” | Identify the sample, formula, product amount, application motion and the lines observed; compare the revision under the same conditions. | Labelled photographs and the reviewed sample. |
| “Make it softer.” | Describe whether the issue is tip feel, bending resistance, spread or the pressure required for the intended use. | Accepted reference and notes on the comparison. |
| “The logo is wrong.” | Identify the artwork version, location, orientation, size and the discrepancy from the approved version. | Approved artwork and an annotated sample photograph. |
| “Ready for production.” | List accepted details, rejected details and unresolved items before approving an identified revision. | Signed or otherwise agreed approval record and specification. |
Use explicit decisions for each review item.
Mark an item accepted, revision required, or not yet checked. A blank result is not approval. If approval is conditional, identify the condition and who must confirm it. Keep the commercial order scope and technical sample revision connected.
Separate a sample review from batch acceptance.
Approval of a sample establishes the agreed reference. It does not prove that every future unit matches it. Agree production inspection coverage, methods, defect handling and any sample-based tests separately; the 28-step process explains the sequence, not a statistical acceptance plan.

A sample is ready for approval when the agreed checks are complete, the accepted version is identifiable and no unresolved issue affects the specification you are releasing. If a detail still needs changing, record the change and the evidence needed to close it. Avoid an unqualified “approved” message while revisions remain open.
| Decision | Record | Next step |
|---|---|---|
| Approve the identified version | Accepted drawing, physical sample, artwork and packaging versions, plus agreed review results. | Confirm the production release and commercial conditions in writing. |
| Request a revision | The affected component, requested change and why the present sample does not meet the brief. | Agree whether a revised physical sample or other evidence is needed before approval. |
| Keep approval on hold | Missing information or an unresolved result, with an owner and next action. | Close the issue before authorising production against that specification. |
Does approving the brush also approve its packaging?
Only if the approval explicitly includes that packaging version. A loose brush does not demonstrate the fit of a sleeve, case or set insert. Check the packed sample separately, including head clearance, removal, logo orientation and the agreed contents.
What should be checked again after a revision?
Recheck the changed feature and anything it can affect. A new head dimension may change application and packaging clearance; a handle finish may change the appearance of the logo. Agree the scope of the repeat review rather than carrying every earlier result over to a different construction.
How should care instructions enter the review?
Record the cleanser, washing method and drying position used, then examine the dry sample for changes to shape, finish and connections. Sigma Beauty’s published care guidance cautions against excessive soaking and recommends drying brushes flat or at a slight downward angle. Treat this as general care context, not a validated procedure for every custom brush. Agree instructions for your selected materials and construction.

What should the written approval say?
Identify the product code, sample revision and date; link the agreed drawing, material specification, artwork and packaging; record the checks completed and any exclusions. State who is approving the version and what production scope is authorised. Keep requested changes separate from accepted details.
For a two-ended design, review each end individually. See the UP068 packaging checks or the UP049 formula-review questions for product-specific starting points.

Powder and foundation references need different application reviews even when they share checks for dimensions, connections, finish and packaging.
