Frequently Asked Questions

Compatibility depends on the bottle neck, closure and gasket, not the square body shape. Match the dropper to the exact neck specification and confirm pipette length and leakage on an assembled sample.

The current Bright Glassware range includes dropper-bottle models in 15ml, 20ml and 30ml formats, with some series covering multiple capacities. Choose the size only after confirming the intended fill volume, bottle dimensions, dropper assembly and retail-pack requirements.

Yes. Pumps, caps, lids, stoppers, reeds and other accessories should be matched to the exact container models in the range. Compatibility is determined by the neck finish, opening, rim geometry, insertion depth, gasket or liner and the intended use—not just by a nominal diameter or visual similarity. For multi-size ranges, some components may be shared when the interface is identical. Keep a component reference for every approved model and test the assembled product before using one accessory across several containers.

In many projects, component colors and finishes can be coordinated with the bottle or jar design. The available route depends on the component material and may involve painted, plated, anodized, printed, molded-color or natural-material finishes.

Approve physical color and finish samples under consistent lighting. Metallic and natural materials can appear different from a Pantone chip or screen rendering, so the assembled bottle, jar or closure set should be the final visual reference.

Separate accessory orders may be possible, but compatibility must be confirmed before production. Provide the Bright Glassware model number or the exact bottle or jar opening/neck dimensions, required material and finish, quantity and, when possible, a drawing or physical sample.

Do not assume an accessory will fit only because the nominal diameter looks similar. Opening geometry, thread or insertion details, tolerances and component construction should be checked on representative samples.

Dip-tube length should be matched to the internal bottle height and base shape so the tube reaches close to the bottom without being forced against the glass. A tube that is too short can leave product inaccessible; a tube that is too long can bend excessively or affect pump assembly.

Confirm the final tube length on an assembled sample and test priming and spray performance with the intended fragrance.

Each lid material behaves differently. Wood, bamboo and cork can show natural grain, tone and moisture-related variation; resin supports decorative molded forms; metal and alloy lids can provide precise shapes and metallic finishes but may require inserts or liners for the intended fit.

Select the material together with the jar opening, lid-seat geometry, weight, decoration and packing. Approve physical jar-and-lid samples because the same nominal diameter can fit differently depending on the insert, gasket and manufacturing tolerance.

Provide the exact container model whenever possible. If a model is not available, measure the finished opening or neck and include the dimensions that control component fit: outside and inside diameter, thread or crimp specification, rim or lid-seat geometry, relevant heights and any insertion depth.

For pumps, also provide the neck finish and required dip-tube length. For lids and stoppers, a technical drawing or physical sample is strongly preferred because nominal diameter alone does not describe threads, tapers, gaskets, inserts or fit tolerances.
