Key features & specs

How it compares

Unlike many refillable deodorants that use aluminum cases or require frequent cleaning, By Humankind's bamboo-fiber case is lightweight, biodegradable at end of life, and naturally antimicrobial. Compared to standard plastic-free sticks, this system offers a larger refill size (2.1 oz) and a wider scent range that appeals to those wanting natural fragrance options.

How to use it

1. Unpack the case and one refill from the paper packaging.
2. Hold the case in one hand and push the refill stick up from the bottom using the built-in base.
3. Apply a thin layer to clean, dry underarms with 2-3 swipes.
4. Let the product absorb for about 20 seconds before dressing.
5. Store the case in a cool, dry area; avoid leaving it in a hot car or direct sunlight.
6. When the refill is empty, order a new two-pack and repeat the process.
