Both are bottle products. Both want a bottle this shelf does not hold.

What an e-liquid bottle is

A soft polyethylene body, a narrow dispensing tip, and a cap. It is dispensed by squeezing, usually into a tank through a small opening.

Which rules out everything on this shelf

74 glass containers. Glass does not deform, so there is no way to drive liquid through a narrow tip with it.

A dropper is the closest substitute

41 dropper assemblies here, and a pipette does deliver into a small opening. It is slower, it is two hands, and it is not what the category uses.

Nicotine salts are the same container problem

A different formulation at a different strength in the same physical package. Nothing about the salt changes the bottle.

19 CT CRC closures out of 215 on this shelf. Nicotine products commonly carry child-resistant requirements and the requirement is not described here.

And there is no child-resistant dropper

The tinctures property measures this on the same shelf: droppers and child-resistant closures are separate families with no overlap.

Capacity is the one thing that fits

10 to 120 mL with a median of 30, which is squarely the e-liquid range. The window is right and the material is not.

Light matters less here than for the other group

An e-liquid is consumed over weeks rather than stored, so the 42 amber, blue and frosted containers on this shelf are solving a problem this leaf barely has.

What a buyer should actually look at

The 24 LDPE containers in the same capacity window, two of which carry a dripper tip neck. They are in our catalog and not indexed to this group.

Viscosity is the other reason the material matters

An e-liquid is thin, so it runs out of a wide opening and needs the restriction a dispensing tip gives. A plain continuous thread lid on a glass bottle offers no restriction at all, and 102 of the 215 closures here are exactly that.

Which is the honest recommendation

Ignore this shelf for these two leaves, and ask for the polyethylene. The next page lists what is there.

The Davis Pack Supply catalog, measured 19 October 2026. All 74 containers indexed to this group are glass, with no plastic of any kind. 69 are bottles and 5 are jars, and 60 of the bottles are glass boston rounds. Capacity runs 10 to 120 mL with a median of 30. Among the 215 closures there are 41 dropper assemblies, 3 euro droppers, 2 orifice reducers, 1 dropper tip cap, 19 CT CRC child-resistant closures and 102 plain continuous thread polypropylene lids.

The Davis Pack Supply catalog, measured 19 October 2026. Catalog-wide, 24 LDPE containers and 44 HDPE containers sit inside the 10 to 120 mL window this group's archetype specifies, 68 polyethylene containers in total, and none of them are indexed to this group. The LDPE set includes boston rounds and cylinder rounds from 10 to 118 mL, and two of them carry a 20-410DT neck. The archetype lists Glass as a preferred material and forbids nothing, so glass outscored polyethylene and filled the shelf: a preference became an exclusion.

Written from 15 U.S.C. 375 and 18 U.S.C. 1716E and from the catalog as it stood on 19 October 2026. Nothing here states whether any particular product or container is an electronic nicotine delivery system, and nothing here addresses registration, reporting or age-verification obligations, the Postal Service rulemaking that followed, or state law. Every container indexed to this group is glass, and an e-liquid bottle is squeezed: the 24 LDPE containers inside the same capacity window exist in our catalog and are not routed here.
