What we actually stock for this

The shelf, measured
Five hundred and twenty-six containers from 5 ml to 946 ml, of which 373 are PET and 153 HDPE, with 225 closures. The dominant neck is 24-410 at 196, followed by 20-410, 38-400 and 28-410. Nothing on it is glass, which is the use deciding the material.
Why no glass
These bottles are carried in trunks, dropped on driveways and used on concrete. Breakage resistance outweighs the inertness glass would offer, particularly as the contact times here are months rather than years.
PET where the product is shown
Clear, light, labels well, and lets a buyer see a colored liquid, which is a large part of how detailing products are merchandised. It is the default for ready-to-use sprays.
HDPE where chemistry argues for it
More tolerant of solvents and silicones, opaque, and available in squeezable walls. For concentrates and for anything with a harsher solvent load it is the safer starting point.
The small end is for concentrates
The range runs down to 5 ml, which is sample and concentrate territory rather than spray bottles. If you sell a concentrate plus a dilution bottle, both ends of this shelf are in play.
Neck finish decides the trigger
Every container page lists the closures verified against its own neck. With 196 containers on 24-410 the trigger options are broad, and the chemical compatibility question is separate from and more important than the thread match.
The shelf is wide because the category is
Glass cleaner, wheel cleaner, interior dressing, drying aid and a concentrate are five different products a single maker will want in a matching range. That is why the usable set here runs into the hundreds rather than the dozens, and why neck finish consistency across a range is worth deciding early.
