The other hand is holding tweezers. That is the whole closure brief.

What is here

288 continuous thread, 32 disc top, 31 child resistant, 26 spouted, 22 dome lids, 19 lug and twist, 14 phenolic, 13 spice caps, 11 liners and sealing discs and 10 flip top.

Dome lids and lug and twist are the craft closures

22 and 19. A quarter turn or a lift, openable while holding a part, and they go back on without finding a thread.

The 288 continuous thread caps are the default

Reliable, cheap, and two hands. For a jar opened once a session that is fine; for the three jars you open constantly it is friction.

Liners for the things that care about moisture

11 liners and sealing discs. Bearings, weathering powder and anything stored in a garage through a winter all want a seal rather than a cover.

The 31 child resistant closures have a use here

Not required by anything in this property, and the right answer for the magnet jar in a house with small children.

Spice caps for the powder

13 of them. A sift-and-pour closure on a small jar is how weathering powder should be dispensed, over a tray, rather than tipped.

Avoid anything with a dip tube

Pumps and droppers belong to the paint half of this group, which lives in the miniature painting property. A dry parts jar wants nothing mechanical.

One neck across the system

Which is what makes spare lids possible. Choose the container family first and the closure follows it, rather than the other way round.

Check the lid survives being dropped

A bench jar hits the floor eventually. A lid that cracks turns one spill into a container that can no longer be closed.

And buy more lids than jars

They are the consumable. In a forty-jar system the lids are what degrades, gets lost and ends up on the wrong container.

The Davis Pack Supply catalog, measured 19 October 2026. The model parts and paint shelf is 1,136 rows: 646 containers and 490 closures. 5 mL to 2,000 mL with a median of 118; 25 containers at 15 mL or under, 84 at 30 or under, 183 at 60 or under, 336 at 120 or under, 522 at 250 or under. 351 PET, 117 glass, 100 HDPE, 78 PP. 376 bottles, 255 jars, 13 tubs and pails, 2 tubes. 175 clear, 141 white, 101 amber, 61 blue, 60 natural, 47 black. Closures: 288 continuous thread, 32 disc top, 31 child resistant, 26 spouted, 22 dome lids, 19 lug and twist, 14 phenolic, 13 spice caps, 11 liners and sealing discs, 10 flip top.

The archetype behind this shelf is store-small-dry: 15 to 500 mL, wide mouth, no closure requirement, PP and PET and glass, cold, solid, chunky, scooped, with "small dry parts, wide mouth to get fingers in, clear so you can see what is inside" as its stated reason. Eleven of the twelve leaves are dry parts, so the archetype describes the craft correctly, which is uncommon in this library.

Written from 16 CFR 1501.4 and 16 CFR 1262, and from the catalog as it stood on 19 October 2026. No cylinder dimensions appear anywhere in this property, because the rule gives them in a figure rather than in its text. Whether a particular part or magnet passes either test is a determination about that article; we sell the container it is kept in. Whether a kit is a children's product is the four-factor test covered in the resin jewelry property.
