01Start with an exact complete-bottle reference
This directory is for buyers selecting a photographed bottle-and-cap presentation. It is distinct from the black-body bottle directory, which groups bottle color, and from the standalone cap guide, which begins with a separate closure component.
02Compare cap shape and proportion before finish details
Straight cylinders, domes, spherical caps, T-shaped forms, pebble profiles and faceted directions change the assembled silhouette. Shortlist the exact SKU first so cap height, projection and bottle proportions remain traceable.
03Keep mixed black-trim directions explicit
Some published references show black combined with gold-tone or silver-tone trim. Treat the exact product photograph as the visual boundary and state whether an all-black, black-trim or mixed-metal direction is required.
04Confirm the component assembly rather than assuming fit
A similar-looking black cap does not establish the bottle neck, insert, pump or collar specification. Confirm the selected bottle, neck, pump, collar, cap construction and finished assembly together before approval.
05Send one quote-ready bottle brief
Include the exact OULU SKU, quantity, destination, desired black-cap direction, pump and collar needs, decoration, fitted box requirements and target timing. Live availability, MOQ, price and schedule are confirmed for that defined scope.
