Five families hold 171 of 251 rows. Eleven hold one each.

The 251 containers on this shelf fall into twenty five families

Which is more than it looks like from the top of the list, because the distribution is extremely uneven.

Five families carry 171 of the 251 rows

PET Single Wall Jar at 101, PP Single Wall Jar at 26, Double Wall Round Base Jar at 22, glass straight sided jar at 20 and glass boston round at 15. So two thirds of the shelf is five shapes.

Nine more families carry between two and thirteen rows

Double Wall Straight Base Jar at 13, PP round tub at 12, glass mason and paragon at 10, glass hex at 7, plastic spice bottle at 4, French square at 3, PET jar set at 3, PET oval jar at 2 and PP hinged container at 2.

And eleven families carry exactly one row each

PET Cylinder Round, PET spray bottle, HDPE Packer Bottle, PET Packer Bottle, Honey Container, Glass Tapered Jam Jar, Glass round lug jar not straight, Glass low profile jar, PP thick wall jar, Lip balm tube and Deodorant Container.

Which is the tail of a catalog built for other purposes

A honey container, a lip balm tube and a deodorant container are on a small parts storage shelf because they fit a neck finish that is on it, not because anybody chose them for ballast or couplers.

The subcategory field tells the same story at a different grain

Eighteen subcategories, and seven of them hold one row: Cylinder Rounds, Deodorant Tubes, Honey Bottles, Lip Balm Tubes, Low Profile Jars, Spray and Trigger Bottles and Thick Wall Jars.

An earlier pass on this shelf got both counts wrong and it is worth saying how

It reported fourteen families and fourteen subcategories. Both figures came from a listing that had been truncated to its fourteen largest entries, and the truncation was read as a total.

Which is a specific and avoidable kind of error

A count taken from a display rather than from the data. The fix is to count distinct values directly, and the corrected figures of 25 and 18 were taken that way on 19 October 2026.

The correction changes how the shelf should be read

Fourteen families with an even tail is a shelf of fourteen options. Twenty five families where eleven hold one row is a shelf of fourteen options plus eleven oddments, and those are different things to plan against.

And one of those eleven oddments turned out to carry a contradiction

Which is the next page, and it is the reason the family field should not be relied on for what the material is.
