A dropper bottle is really two decisions: the glass or resin that protects the formula, and the closure that meters it. TWO Packaging supplies both as one printed, assembled unit — amber UV and flint glass, PET and HDPE, dropper assemblies, pump and mist caps, and certified child-resistant closures — priced on request at about $0.35–$2.50 each.
Amber blocks UV, flint shows the product, PET drops the shipping weight and the breakage rate. If the formula is light-sensitive — most botanical extracts and vitamin oils are — amber or an opaque secondary carton is the honest answer, not a clear bottle that looks better on a shelf.












A dropper bottle is only as good as what sits on top of it. Graduated pipettes meter a dose, pumps suit lotions and serums, mist caps suit facial and room sprays, and a certified child-resistant cap is required for a long list of categories. Ours are CR certified.










Most dropper bottles are decorated with a pressure-sensitive label; a shrink sleeve wraps a curved shoulder that a flat label will not sit on. A tamper band across the cap is a separate part and is worth the fraction of a cent it costs on anything ingestible.




Start with the fill volume and work outward. A 30 ml formula in a 30 ml bottle leaves no headspace for the pipette to displace, so it overflows the first time a customer inserts the dropper. Specify the bottle one size up from the nominal fill, or accept a part-filled look on the shelf.
Pipette length is measured to the bottle's internal depth, not its external height. Too short and the last fifth of the product is unreachable; too long and the pipette bottoms out and bends. We set this on the drawing and you confirm it on the pre-production sample — it is the single most common thing brands discover too late.
Neck finish is the other number that matters. It is written as diameter and thread pitch (20-400 and 24-410 are the common ones in this range) and it has to match between the bottle and every closure you might want later. Lock the neck finish early and you can change caps freely; change it later and every closure in your warehouse is obsolete.
Finally, decide whether the bottle ships naked or in a carton. A naked bottle needs a durable label and a tamper band. A cartoned bottle can carry a cheaper label and use the carton for the regulatory copy, which frees the bottle face for the brand.
Essential oils attacking the bulb. Standard rubber bulbs degrade against citrus and other terpene-heavy oils — the bulb swells, discolours and eventually crumbles into the product. If the formula is oil-based, specify a chemically resistant bulb and say so at quote stage.
Labels that will not lie flat. A Boston round is straight-sided and takes a label cleanly. A tapered or shouldered bottle will wrinkle a flat label every time. That is a shrink sleeve job, and it costs more than the label you were budgeting for.
Assuming amber is decorative. Amber glass is a UV filter, not a colour choice. If the formula is light-sensitive and you ship clear glass because it photographs better, degradation starts on the shelf and the customer blames the formula.
Ordering the cap separately, late. Bottles and closures have different lead times. Order them together and they arrive together; order the cap after the bottle lands and you hold inventory you cannot fill.
Material is the first lever. Glass costs more than PET per unit and considerably more to ship, because it is heavier and needs more protection in the case. On a direct-to-consumer product, the freight and breakage difference can outweigh the unit price difference entirely.
The closure is often the larger half of the cost. A plain screw cap is cents; a graduated glass pipette with a chemically resistant bulb and a certified child-resistant mechanism is a multiple of that. Specify the closure you actually need rather than the one on the nicest photograph.
Decoration is the third lever. A single-colour pressure-sensitive label is the cheap end. A full-wrap shrink sleeve costs more but is the only option on a tapered bottle. Foil, spot UV and textured facestocks each add a pass.
Volume moves all of it. The jump from 1,000 to 5,000 units is the single largest percentage drop you will see, because the fixed setup is spread across five times the run. Quotes here are all-in — tooling, printing, finishing and packing in one number — and reorders carry no setup fee, so the second run of the same artwork is always cheaper than the first.
Every decoration below runs on cartons, labels and shrink sleeves. Pantone spot matching is standard, not an upcharge tier, and artwork files stay on record for 24 months so a reorder is a single email.












Send the fill volume and the viscosity. Viscosity decides the closure more than the bottle does — a thin tincture and a thick serum want different pipette bores.
About $0.35 to $2.50 per bottle depending on material, size and closure. Quotes are all-in, with no setup fees on reorders.
Quantities are priced on request, and multiple SKUs can share a production run.
15 ml to 120 ml covers almost every tincture, serum and oil. Send your fill volume and we'll spec the bottle and the pipette length together.
Yes — certified child-resistant screw caps and locking lids.
Amber if the formula is light-sensitive, which most botanical and vitamin oils are. Clear or flint if product visibility matters more and the bottle ships inside a carton.
Bottles are decorated with pressure-sensitive labels or shrink sleeves rather than printed directly. A shrink sleeve is the right call on a curved or tapered shoulder.
20-400 and 24-410 are the common finishes in the 15–120 ml range. Lock the neck finish early — it has to match every closure you might want later, and changing it makes existing caps obsolete.
A standard rubber bulb degrades against citrus and other terpene-heavy oils. For oil-based formulas we specify a chemically resistant bulb — tell us the formula at quote stage.
Yes — one quote, one lead time, one delivery, rather than three vendors that arrive out of sequence and leave you holding unfillable inventory.
24 months. A reorder of the same artwork is a single email with no setup fee.
