A hundred and seven of two hundred fifty one

This group draws on 107 containers and every one of them is on the shared shelf
A strict subset of the 251 that nine groups use identically, with no rows of its own. So 144 rows are excluded.
And the exclusion is not even across the three materials
The base shelf holds 117 PET, 78 polypropylene and 56 glass. This shelf keeps 83 of the PET and 24 of the glass.
It keeps none of the polypropylene
All 78 rows excluded. Not most of them, not a strong majority: every one. Which is the only categorical material exclusion anywhere in this library.
Which makes it a rule rather than a pattern
Elsewhere an exclusion is a tendency with exceptions. The quilting shelf excludes 70 rows and only half of those by size, with no clean rule behind the rest. This one has a rule and it holds without exception.
Two whole categories are gone as well
Every tub and pail, which is 12 rows, and both tubes. What remains is 99 jars and 8 bottles, from four categories on the base shelf.
And all 24 rows recorded as Natural are gone, which follows
Natural denotes unpigmented polypropylene, so excluding the polypropylene excludes the color. The color exclusion is a consequence of the material one rather than a separate decision.
The capacity band is closed at both ends too
The base shelf runs 5 to 500 mL across 29 distinct values. This shelf runs 30 to 354.882 across seventeen. Twenty two excluded rows sit below 30 mL and 35 above 355.
So four fields narrow at once and they narrow consistently
Material, category, color and capacity. A shelf of clear or colored PET and glass jars between 30 and 355 mL, and nothing else.
Which looks like a shelf selected for how it presents
Polypropylene is opaque or translucent and reads as utilitarian. A tub is a tub. And a 5 mL jar and a 500 mL jar are both wrong for a favor. That is a coherent reading of the selection.
And it is offered as an explanation rather than as a recorded fact
Nothing in the record states a reason for any exclusion. The counts are measured and the reason is inferred, and the page keeps those two apart because every other property in this library does.
What a curated shelf cannot show you is the whole theme of this library
This is the clearest instance of it. A buyer standing on this shelf cannot see that 78 polypropylene containers exist one routing decision away, and reading the absence as a supply fact would be wrong.
