Key features & specs

How it compares

By Humankind's deodorant refills differentiate themselves from competitors like Native and Meow Meow Tweet by using a reusable case made from 50% recycled plastic and offering completely compostable refill cartridges. The eucalyptus spearmint scent is more herbaceous and complex than typical mint deodorants, appealing to those who dislike floral or fruity options.

How to use it

1. Unwrap the paperboard refill and push it into your existing By Humankind case until it clicks.
2. Twist the base to raise the deodorant stick by a few millimeters before each use.
3. Apply in two to three gentle strokes under each arm — a little goes a long way.
4. After the refill is empty, compost the paperboard tube in your municipal compost bin.
5. Wipe the case clean with a damp cloth between refills to maintain hygiene.
6. Store the deodorant in a cool, dry place to keep the coconut-oil base from melting.
