1. Define what is actually being supplied
State whether the quotation covers an empty bottle, a complete assembled bottle or a bottle with separately packed accessories. List the body, screw closure, dispensing tube or nozzle, and any protective cover individually. A cap shown beside a bottle may be a different accessory rather than a tip cover.
Separate the empty-container specification from any liquid product specification. Ask the supplier to identify the intended contents and use restrictions. A bottle selected for one purpose should not automatically be approved for another formulation, temperature or handling method.
2. Clarify the capacity of the lash rinse bottle
Ask what the stated capacity represents and how it is measured. Nominal size, recommended working fill and brimful capacity are different purchasing references. Use a documented method agreed with the supplier when comparing samples; do not derive capacity from image proportions.
Record the external dimensions as well. A bottle may have a suitable volume yet fail to fit a retail pouch or shelf because the bent nozzle extends above or beside the body. Check the complete assembly in the planned kit, including the closure and protective packaging.
| Component | Buyer question | Retained evidence |
|---|---|---|
| Bottle body | What material and capacity definition apply? | Specification and sample reference |
| Closure | Which body/neck version is approved? | Matched part references |
| Nozzle or tube | What assembly and orientation are specified? | Assembly instructions and photos |
| Loose accessory | What is its intended function and fit? | Named component list |
| Retail pack | Does the full assembly fit without pressure? | Approved packing layout |
3. Match the closure, tube and nozzle
Obtain the component references and assembly instructions. Review the neck and closure fit, nozzle orientation and the attachment method without forcing parts together. Where a dip tube is part of the design, request its specified configuration rather than assuming every bottle uses the same internal arrangement.
For replacement components, ask for written confirmation of compatibility with the approved body. Keep a sample of the matched assembly. A similar thread diameter, color or product photograph is not a sufficient substitute for a compatibility check.
4. Agree a sample leak-check method
Define the check conditions with the supplier before testing: permitted test medium, fill level, closure method, position, duration and acceptance criteria. Keep this as a procurement evaluation of the sample. It is not a universal procedure for bottles or a substitute for formal product qualification.
Record where any seepage or dripping occurs so the supplier can distinguish a closure issue from a nozzle or assembly issue. Do not report “leakproof” on a label because one sample passed a short check. Ask what evidence supports any performance wording proposed for the finished packaging.
5. Obtain use and care information
Request instructions for filling, emptying, storage and care that apply to the exact bottle material and assembly. Clarify whether the item is intended for repeated use and which components can be removed. Do not infer cleaning-agent compatibility from translucency or flexibility.
Keep container instructions separate from cleanser directions and service protocols. This article does not recommend rinsing liquids, pressure, temperatures or treatment steps. Your customer-facing instructions should match the supplied product and its supported intended use.
6. Check labeling and packaging as a system
Review the physical label area on the sample, including the curved shoulder and any flexible surface. Compare the approved artwork against the assembled bottle so important information is not hidden by the grip area, closure or retail insert. Leave capacity and material claims unresolved until verified.
Inspect how the nozzle and any loose parts are restrained inside the kit. For shipment qualification, discuss the actual package and route with a packaging specialist. ISTA’s procedure overview provides different testing categories; selecting one does not itself demonstrate that this bottle or kit has passed it.
| Observation | Record | Decision |
|---|---|---|
| Cap or nozzle mismatch | Affected parts and sample codes | Hold assembly approval |
| Leak-check concern | Agreed conditions and observed location | Ask supplier for corrective evidence |
| Kit fit conflict | Complete assembly dimensions | Revise insert or product selection |
| Changed component | Old/new revision references | Repeat the relevant sample checks |
7. Control the lash rinse bottle reorder specification
Save the body, cap and nozzle references, dimensions, capacity definition, artwork revision and packaging layout. List pack counts using clear units: complete bottles, loose closures, inner packs and cartons. Avoid a quotation that uses “pieces” for both a complete assembly and individual components.
Ask the supplier to flag material, mold, nozzle, closure or packing changes before repeat production. Compare the new sample with the recorded assembly and resolve differences before acceptance. A controlled specification is more useful than ordering by a photograph alone.
Prepare a sample inquiry
Bring your component list, intended configuration, quantities, destination and open questions to the FanLash wholesale inquiry team. Ask which options are currently available and what evidence is needed before approval. Availability, pricing and terms require confirmation for the requested item.
For the broader approval process, review our lash quality-control framework and lash sample planning guide; accessory-specific terms still need to be agreed.
Frequently asked questions
Is a lash rinse bottle the same as a foam pump bottle?
No. They use different dispensing arrangements and should have separate component specifications. Do not transfer a foam-pump approval to a rinse-bottle assembly.
Does the listed capacity prove the intended fill volume?
Not by itself. Ask whether the number is nominal, working or brimful capacity, and record the agreed reference and measurement method.
What should be checked when changing a nozzle?
Confirm the exact body and closure compatibility, assembly instructions, complete dimensions, agreed sample checks and packaging fit.
Does an empty rinse bottle need care instructions?
Buyers should obtain instructions for its supported intended use, filling, emptying, storage and care. Empty-container status does not establish compatibility with every liquid or cleaning method.
