What we actually stock for this

The shelf, measured
Sixty-three containers from 7 to 120 ml, all 63 of them glass, with 186 closures verified against their necks. It is one of the smaller shelves in this library and the only one with no plastic container on it at all.
Why there is no plastic bottle here
Fragrance and essential oils soften, swell and craze many polymers, and 1700.15(a) asks special packaging to keep performing in actual contact with the substance. Glass removes the bottle from that argument entirely.
The closure is still plastic
And so is the liner and the reducer, so the compatibility question has not gone away, it has narrowed to three small parts. Those are the parts to test, and they are cheap enough to test properly.
Neck finishes
The dominant finish is 20-400 at 31 of the 63, then 24-400 at 8 and 38-400 at 5, with 22-400, 18-400 and 43-400 behind them. A range built on one finish buys one closure in volume, which matters more at this scale than at any other.
Colors
By color the shelf runs 17 clear, 14 blue, 13 amber, 8 frosted, 4 white, and 2 each of purple, red and green. Clear shows the liquid and the reeds; amber and blue reduce the light reaching it.
Where to settle the closure
Every container page lists the closures verified against its own neck, so the thread match is already done. What is left for you is compatibility with the blend and, if a threshold applies, tested child-resistant performance.
A small shelf is easier to standardize on
Sixty-three bottles across four formats means the choices are narrow enough to settle in one sitting, and 31 of them share a finish. A range built on 20-400 buys one closure, one liner and one reducer in volume, which is the economics that matters at this size.
