01Start with the complete photographed bottle
This collection is a shortlist of assembled bottle-and-cap references, not a standalone cap inventory. Keep the exact SKU and photograph with the enquiry so capacity, bottle shape, cap silhouette, collar and shown dimensions remain traceable.
02Treat crystal-style as a visual description
A transparent faceted or crystal-style appearance does not establish natural crystal, glass, acrylic, resin or another material. State the required clarity, shape, color, finish and durability target so the applicable construction can be reviewed.
03Compare cap form, color and transparency
T-shaped, faceted, stepped, pedestal, square, block and low-profile caps create different assembled proportions even when all appear transparent. One reference uses a transparent-blue direction, so compare cap color as well as the cap against the bottle neck, shoulder, body and overall height before shortlisting.
04Confirm the complete component assembly
A similar-looking transparent cap does not prove compatibility with another bottle. Confirm the selected bottle neck, pump, collar, cap insert, orientation and assembled dimensions together before sample approval or fitted-box development.
05Send a quote-ready SKU brief
Include the exact OULU SKU, quantity, destination, preferred clear or crystal-style direction, pump and collar requirements, decoration, box needs and target timing. Availability, MOQ, price and schedule are confirmed only for that defined scope.
