363 continuous thread, and for an alcohol ink the liner is the product.

What is here

363 continuous thread, 43 dropper assemblies, 27 dome lids, 19 lug and twist, 16 flip top, 14 phenolic, 11 liners and sealing discs, 8 specialty, 6 dropper tips and caps and 6 round tubs.

Droppers for the colorants

43 assemblies plus 6 dropper tips and caps. A drop is the dose for a resin dye, and the dropper is what makes a repeatable color possible.

With the usual elastomer problem

An alcohol ink or a solvent-borne dye attacks a bulb. The bulb perishes, the ink climbs into it, and the dropper stops being accurate before it stops working.

Phenolic where the liner has to hold

14 of them. The traditional closure for a solvent, and the one to ask about when a colorant is evaporating.

Dome lids and round tubs for the dry stores

27 and 6. Wide, quick and openable with one hand, which is what an inclusion jar needs when the other hand is holding tweezers.

Lug and twist for the shallow jars

19 of them. A quarter turn and a flat seal, which suits a mold store where the lid comes off every session.

The liners are the quiet line item

11 liners and sealing discs. For a pigment that evaporates or a powder that cakes, this is the part that fixes it, and it is the part nobody orders.

Standardize the neck across the collection

A pigment collection with four neck sizes is a drawer of mismatched caps. One neck across the small jars and one across the small bottles is worth more than the perfect bottle for each.

And buy spares

Caps and droppers are consumables in this craft: they get sticky, they perish, and they get lost. Ordering twice as many as bottles is normal rather than wasteful.

What a closure cannot fix

A resin chart problem. If the colorant attacks the bottle, no closure helps, and that is the decision the archetype puts first.

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 four leaves sit on it, including the two that store dry items picked out with tweezers.

Written from 15 U.S.C. 2052(a)(2), 15 U.S.C. 2063(a)(5) and 15 U.S.C. 1278a, and from the catalog as it stood on 18 October 2026. Whether a particular piece is a children's product, and whether a particular encapsulation is an inaccessible component part, are determinations this property raises and does not make. State jewelry laws and voluntary standards for children's jewelry sit on top of everything here.
