Deodorant stick

Also written as natural deodorant, deodorant packaging, twist-up stick.

A solid or soft-solid in a twist-up barrel. Natural formulations are softer than conventional ones and behave differently in the pack.

What it needs from a bottle

Softer formulas slump in a wide barrel and smear on the first turn. Narrower barrels and a tighter elevator thread handle a natural formula better, and it is worth sampling the actual formula in the actual stick before ordering.
