01Start with an exact complete-bottle reference
This collection is for buyers comparing a photographed bottle-and-spherical-cap presentation. It is separate from the standalone cap guide, which begins with a loose closure component, and from the bottle-shape guide, which classifies the glass body rather than the cap.
02Use spherical or ball cap as a geometry direction
Ball cap and globe cap describe the visible closure form in these references. That appearance does not establish resin, acrylic, metal, natural wood, stone or any other material. Keep the exact SKU and photograph with the enquiry, then state the required color, surface and construction direction.
03Compare the complete assembled proportion
A spherical cap can be compact, oversized, wood-look, marble-look, colored or combined with visible trim. Review the published bottle dimensions and complete shown height before approving artwork, shelf presentation, a fitted insert or an outer carton.
04Confirm neck, pump, collar and cap compatibility
Similar spherical caps should not be assumed to fit another bottle. Confirm the bottle neck, pump, collar, cap insert, orientation and assembled dimensions for the exact SKU before sample approval or packaging development.
05Send one quote-ready project brief
Include the exact OULU SKU, quantity, destination, required cap direction, pump and collar needs, decoration, box requirements and target timing. This collection does not imply one live quantity, MOQ, price or schedule for all references.
