Three of the six crafts here are jar crafts, and the archetype says narrow mouth.

Why they are jars

A brush is pushed into soap, a pigment is picked up on a brush tip, and basing grit is poured out or scooped. None of those is a pour through a narrow neck.

What is here

281 jars of the 793 containers: 132 PET single wall, 33 PP single wall, 24 glass straight sided and 22 double wall round base, with 27 dome lids and 19 lug and twist closures for them.

The straight sided glass jar is the good one

24 of them. Inert, heavy enough not to tip, a wall a label wraps cleanly, and a mouth wide enough for a brush. It is also the smallest set in this group.

Single wall PET is the volume answer

132 containers, light and cheap, and fine for a water-based soap or a dry grit. For a pigment that will be handled daily the glass jar feels like a different product.

Double wall is a cosmetic look

22 of them, a jar inside a jar, which reads as premium and wastes volume. For a pigment line sold on presentation it is a real option.

Fill low for a powder

A jar filled to the rim is a jar that dusts when opened. Filling to two thirds is the difference between a usable pigment and a cloud on the desk.

Which is also the labeling connection

A powder sold by weight falls under the 28 g half of the small container clause, and inhalation is the exposure route the chronic hazard labeling exists to address. The smallest jar may need the fullest label.

The lid has to seal flat

A dome lid that seals on the land and a liner that does not shed are what keeps a powder in. A lid that seals on the thread alone will leak dust down the side.

Basing material is bulk, not small

Sand, ballast and flock are sold in volumes where the 13 tubs and pails on this shelf matter more than the jars. This is the one leaf the industrial window actually fits.

So the archetype is half right

Narrow mouth and poured describes the paint and the primer. For the other three leaves the jar shelf is the shelf, and reading the group as a bottle group hides 281 containers.

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(b)(7). Where the Commission determines that an art material "in a container equal to or smaller than one fluid ounce (30 ml) (if the product is sold by volume) or one ounce net weight (28 g) (if the product is sold by weight) has the potential for producing chronic adverse health effects with customary or reasonably foreseeable use despite its small size", the Commission "may require the art material to carry a label which conveys all the information required under the standard referred to in subsection (a) as modified by this subsection for art materials in a container greater than one fluid ounce or one ounce net weight". law.cornell.edu

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.
