The twenty four

The count
24 LDPE containers sit inside the 10 to 120 mL window this group's archetype specifies. A further 44 HDPE containers sit in the same window, making 68 polyethylene containers in total.
None of them is indexed to this group
Which is the finding. Not a sourcing gap and not a data gap. The right container is in the catalog and the index sends something else.
What the LDPE set looks like
Boston rounds and cylinder rounds from 10 mL to 118, in natural and white, on 13-415, 15-415, 20-410 and 24-410 necks.
And two carry a 20-410DT neck
DT is the dripper tip family, which is the finish built for a squeezed dispensing tip. Two containers, exactly on point, not shown here.
Natural polyethylene is translucent
Which an e-liquid user will tell you is a feature, because the level is visible. It is a trade against light exposure that this category usually accepts.
The HDPE set is stiffer
44 containers in the window, which squeeze less readily than LDPE. For a dispensing tip LDPE is the softer and better answer.
Why the index did this
The archetype for this spoke lists Glass as a preferred material and forbids nothing. Glass scored higher and filled the available slots.
So a preference became an exclusion
Which is the mechanism worth remembering. A ranked list with a cap behaves like a ban whenever the preferred option is plentiful.
And it is invisible from the shelf
A buyer looking at 74 glass bottles has no way to know that 68 polyethylene containers in the same size window were outranked rather than absent.
Which is why the number is published
Ask for the polyethylene. It exists, it is in the right window, and the two dripper tip necks are the ones to ask about by name.
