43 dropper assemblies out of 646 closures, for the dispensing method this entire hobby uses.

What is here

382 continuous thread, 43 dropper assemblies, 32 disc top, 31 child resistant, 27 dome lids, 26 spouted, 19 lug and twist, 17 flip top, 14 phenolic and 13 spice caps.

The dropper is the craft

A painter takes two drops of paint and three of medium onto a wet palette. Drop counting is how recipes in this hobby are written, and it needs a dropper rather than a cap.

43 is thin and worth stating

It is a real set and it is a small one against 646 closures. For the dispensing method the craft is built around, the shelf is narrower than the total suggests.

Match the dropper to the neck

20-410 is 96 containers and 24-410 is 149, which are the two necks a small bottle in this catalog is most likely to have. A dropper that does not match the finish is not a closure.

And to the liquid

A dropper bulb is elastomer and a solvent attacks elastomer. For a lacquer or a thinner the bulb is the first thing to perish, which is an argument for a plain lined cap and a separate pipette.

The 31 child resistant closures

The archetype marks this craft child resistant, and the statute requires a chronically hazardous art material to carry "a statement signifying that such art materials are inappropriate for use by children". Those two reinforce each other.

Which is not the same as a legal requirement to use one

Child resistant packaging is required for specific substances by their own rules. The archetype flags it as prudent for a solvent in a hobby house, and that is the honest way to put it.

The liner is the specification people skip

A continuous thread cap is 382 of the closures here and its liner decides whether a solvent stays in the bottle. Specify it explicitly or expect evaporation.

Dome lids and jars

27 dome lids and 19 lug and twist, for the pigment and brush soap end. A powder wants a lid that seals flat and opens without a shock.

What to settle first

The dispensing method, because it decides the neck, and the neck decides the bottle. Picking the bottle first and hoping for a dropper is the commonest wrong order.

The Davis Pack Supply catalog, measured 18 October 2026. The miniature painting shelf is 1,439 rows: 793 containers and 646 closures. 5 mL to 9,464 mL with a median of 118; 41 containers at 15 mL or under, 115 at 30 mL or under, 228 at 60 or under and 411 at 120 or under. 430 PET, 133 HDPE, 133 glass, 87 PP, 9 steel. 487 bottles, 281 jars, 13 tubs and pails, 9 tins, 2 tubes. 143 amber or dark amber. Closures: 382 continuous thread, 43 dropper assemblies, 32 disc top, 31 child resistant, 27 dome lids, 26 spouted, 19 lug and twist, 17 flip top, 14 phenolic, 13 spice caps.

The archetype behind this shelf is ind-chemical: 100 to 20,000 mL, narrow mouth, HDPE and glass, light sensitive, child resistant, poured, with "chemical resistance is the entire decision, check the resin chart first" as its stated reason. All six leaves in this group sit on it. The window is an industrial one and this craft works at 15 and 30 mL, which is why the shelf reads large for the work.

15 U.S.C. 1277, the Labeling of Hazardous Art Materials Act. Subsection (a) makes the labeling requirements of ASTM D-4236 "deemed to be a regulation issued by the Commission under section 1262(b) of this title". (b)(1) defines an art material as "Any substance marketed or represented by the producer or repackager as suitable for use in any phase of the creation of any work of visual or graphic art of any medium", excluding economic poisons under FIFRA and drugs, devices or cosmetics under the FFDCA. (b)(2) "applies to art materials intended for users of any age". (b)(5) requires the label of an art material needing chronic hazard labeling to carry "the name and address of the producer or repackager of the art materials and an appropriate telephone number and a statement signifying that such art materials are inappropriate for use by children". (b)(6) requires new hazard information to be "incorporated into the labels of such art materials that are manufactured after 12 months from the date of discovery". law.cornell.edu

Written from 15 U.S.C. 1277, 16 CFR 1500.14(b)(8) and 16 CFR 1500.3(c)(6), and from the catalog as it stood on 18 October 2026. Where a requirement turns on a determination the Commission makes rather than on a fixed rule, this property says so. Nothing here is a toxicological review, which is the one thing in this area that cannot be done from a document.
