01Use the pictured KRN-0303 as a traceable starting point
KRN-0303 shows a studded clear glass body and a separate black studded cap. Its published 48 × 33mm footprint, 66mm bottle-body height and 88mm overall height describe the pictured configuration, not its neck finish or a substitute cap.
02Record unknown interfaces before choosing parts
For this 30ml example, ask for the bottle neck drawing revision or sample ID. Keep the proposed pump, actuator, collar and cap insert as separate unselected items until their exact models and assembled sample are reviewed. A shared 13FEA or 15FEA label would not by itself prove fit.
03Keep the surface and closure decisions distinct
State whether the glass studding and black cap studding are both required. Review logo position, cap orientation and assembled clearance on the selected sample; do not treat a cap texture as proof of bottle texture on another SKU.
