A mold is lifted out flat and an inclusion is picked up with tweezers. Neither is poured.

Silicone molds

Flexible, dust-attracting, and ruined by being creased or stored under weight. The requirement is flat, clean and separated.

Dust is the failure

A speck on the mold face is a defect in the casting, and it is invisible until the resin cures around it. A closed container is the only reliable answer.

Which a wide shallow jar can do

The 24 glass straight sided jars and the wider single wall jars take a small mold flat. Beyond a certain size the shelf has nothing, and a lidded box is the honest recommendation.

Never stack them under weight

Silicone takes a set. A mold stored under a heavy jar for a month casts the shape of that pressure, and no cleaning recovers it.

Inclusions are a sorting problem

Dried flowers, foils, charms, beads, shells and findings. Mixed, fragile, chosen by eye, and stored in quantities of a dozen.

So the answer is many small clear containers

Which this shelf can do with the small single wall jars, and cannot do well: a compartment box is the right object and there is not one here.

Dried flowers need to stay dry

Moisture in a dried botanical is a cloudy casting and sometimes a mold bloom. A lined closure and a desiccant sachet is the difference.

And findings are the lead question

If a children's line is in scope, the metal inclusions are the parts most likely to be out of specification. Keeping certified findings in a separate marked container is a sourcing control.

Which is a packaging answer to a compliance problem

Separate storage for documented parts, labeled as such, is how a small maker keeps a children's line and an adult line from mixing on one bench.

The archetype describes none of this

Narrow mouth, poured, chemical resistance, light sensitive. Two of the four leaves in this group are dry storage crafts and the shelf they inherited was built for liquids.

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.

15 U.S.C. 1278a. Subsection (a) sets total lead content for any part of a children's product at "100 parts per million" by weight, and (f)(1) substituted "0.009 percent" for lead in paint on children's products. Subsection (b)(2) provides that the limits "shall not apply to any component part of a children's product that is not accessible to a child through normal and reasonably foreseeable use and abuse", including where the part is protected by a sealed covering or casing that remains intact during normal use. The children's product definition is taken from section 3(a) of the Consumer Product Safety Act. law.cornell.edu

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.
