A structured cosmetic case reference for beauty brands that need the bag to hold its profile rather than collapse like a soft pouch. The shell core, PU surface, corner radius, closure and internal divider must be approved together because each choice changes tooling, packing volume and unit cost.

OEM / ODM PROCUREMENT BRIEF
Engineering a rigid PU cosmetic case
PRODUCT-FIT DECISION
Procurement decision: For buyers seeking a custom rigid PU shell cosmetic case manufacturer, the engineering priority is repeatable formed geometry, corner zipper travel and protected export packing. Choose this construction when shape retention and presentation matter. A soft PU pouch is more suitable when packability and lower shipping volume are the priorities.
COMMERCIAL REFERENCEIndicative FOB Shenzhen price for Custom Rigid PU Shell Cosmetic Case: US$1.20–2.50 per unit at MOQ 500 units. This range applies to the reference construction and standard packing and is valid through 31 December 2026; the final quote is confirmed after dimensions, material, artwork, testing and quantity by colour are approved.
TECHNICAL DATA
Technical specification and OEM controls for Custom Rigid PU Shell Cosmetic Case
The Custom Rigid PU Shell Cosmetic Case values below are reference specifications for RFQ scoping. Dimensions, materials, components and tolerances are frozen only in its signed specification and approved production sample.
Custom Rigid PU Shell Cosmetic Case: reference build and production-control fields
Item / SKU
SH-PU-CB-001
Shell material matrix
Reference build: 1.5 mm cross-grain PU face laminated to a formed structural board
Structural core and construction
Thermo-formed arc shell, perimeter zipper and buyer-defined internal divider layout
Handle, closure and hardware
Metal-look zipper track and pullers; plating and corrosion test scope require project approval
Reference dimensions and tolerance
Reference finished size: 21 x 8 x 13 cm; custom shell tooling changes carton volume. Production tolerances are project-specific and recorded on the approved drawing.
Customisation scope
PU grain, shell radius, debossing, foil mark, divider, puller and protective packing
MOQ and colour matching
MOQ 500 pieces or sets per style; colour is approved from a physical swatch or buyer-named colour standard.
Sample and bulk lead time
Typical catalogue reference: 5-7 days after specification confirmation for sampling and 15-25 days after signed sample/deposit for bulk; reconfirmed in the quotation.
Inspection, audits and certification evidence
Shell symmetry, dents, zipper travel, laminate edge, divider fit and carton recovery. Sampling level, defect classes, tests and any audit/certificate scope are agreed before the PO; no blanket certification is implied.
Rigid-case engineering record
A rigid case cannot be priced reliably from length and width alone. Core thickness, corner radius, mould or forming method and carton utilization change both unit economics and freight.
Shell geometry controls tooling and freight
Approve the shell profile and corner radius before logo placement.
Evidence to retain: Dimensioned shell profile with corner radii
Confirm the core material and PU surface on a cut sample.
Evidence to retain: Cut section identifying the core, lamination and PU surface
Check zipper travel and hardware clearance around the rigid edge.
Evidence to retain: Zipper travel check around the complete perimeter
Pack a trial carton to assess nesting, protection and freight volume.
Evidence to retain: Trial carton showing nesting, surface protection and cubic volume
Alternatives to Custom Rigid PU Shell Cosmetic Case
Provide the longest, widest and tallest contents, divider needs, opening direction, surface reference, logo method, order split and carton constraints. The external profile is then developed around usable internal clearance.
BUYER DUE DILIGENCE
Buyer questions about Custom Rigid PU Shell Cosmetic Case
Why does corner radius matter before logo placement?
It changes the usable flat branding area, zipper path and forming behaviour, so the shell geometry should be frozen first.
Can a rigid shell be packed flat?
Normally no. Test nesting and protective separation in a production-style carton because freight volume can be a major cost driver.
How are dividers approved?
Map the intended contents, divider height, attachment method and removal requirement on the physical sample, then record them in the bill of materials.
What determines whether the formed shell keeps its shape?
Face PU, forming layer, backing, corner geometry and storage pressure work together; approve the complete laminate and formed panel rather than one material alone.
How should zipper travel be checked around a rigid corner?
Load the intended contents and operate both corners repeatedly, checking tooth alignment, pull force and divider clearance at the tightest part of the path.
Which appearance limits belong in shell-bag inspection?
Use signed examples to define acceptable dents, edge waves, surface marks, colour variation and left-to-right shell asymmetry under consistent lighting.
Can this reference be purchased from stock or as one retail unit?
This style is made to order for brands, distributors and corporate programs. We do not sell ready-stock items or individual retail units, and we do not provide dropshipping.
