The short answer
A custom bottle brief should connect brand intent with capacity, closure, equipment, decoration, order volume and delivery requirements. Identify constraints before refining the silhouette.
A mood board helps explain an idea but leaves engineering and procurement questions unanswered. A practical brief lets the supplier identify what can use existing components and what needs development.
Separate requirements from preferences
State the product, approved fill, closure system and equipment constraints first. Then describe the desired silhouette, decoration and visual references. Rank optional features so alternatives can be evaluated without losing the project’s purpose.
Define development deliverables
Agree which drawings, prototypes, samples and reviews are required. Assign responsibility for artwork, closure fit and line trials. Use written approval gates so tooling or decoration does not proceed from an outdated concept.
Procurement checklist
- State mandatory functional requirements.
- Provide visual references with explanations.
- List closure and equipment constraints.
- Define development deliverables and approvals.
- Set a controlled specification revision.
Common question
Should the design brief contain an exact production price?
Provide a target budget and ask the supplier to assess feasibility. The final quotation needs an agreed design, quantity, decoration and delivery scope.
