The leave-on eight

What they have in common
Thick cream or whipped butter, filled warm, scooped rather than dispensed. The archetype describes them accurately, which is unusual enough in this library to be worth saying.
Which is why the mouth has to be wide
Fingers have to reach the bottom corner when the jar is nearly empty, and a narrow neck turns the last fifth of the product into waste. The wide finishes on this shelf, 70-400 at 52 and 89-400 at 27, exist for that.
Filled warm means the material matters
A butter poured warm into a PET jar raises the same question the wax melt shelf raises. Check the published maximum fill temperature against your pour rather than assuming a jar will take it.
Double wall jars for a premium feel
Thirty-one of them. They make a modest fill look substantial and feel considered in the hand, and they cost more per milliliter of product. For a stretch mark balm or a hand cream sold on care, that often pays.
Oils and the liner
A body oil, a massage oil and an oil-heavy butter all sit against the liner for months, and essential oils in them attack several liner materials. Of the 345 closures, 103 carry an HIS liner and 50 an F217.
Glass where the oils are aggressive
Thirty-seven glass containers on this shelf. For a heavily essential-oil-loaded product glass removes the wall from the argument and leaves the cap and liner to test.
Clear sells the texture
76 clear, 49 white, 43 amber, 26 black. A whipped butter looks appealing through clear PET or glass, which is a real part of how this category is bought, and amber protects a light-sensitive active.
