Refillable products are designed so that a reusable component can stay in use while a consumable or worn part is replaced. Depending on the product, that may mean replacing a brush head, adding a new cleaning tablet to a reusable spray bottle, refilling dental floss, or replacing the scent element in a wooden diffuser.

Drop one tablet into a reusable spray bottle filled with water and let it fully dissolve before use. Each tablet is concentrated cleaner in solid form, so you're only shipping and storing the active ingredients rather than a bottle full of water.

One all-purpose tablet makes up to 16 ounces (about 500 ml) of ready-to-use liquid cleaner, enough to fill a standard spray bottle.

Yes. They're formulated without harsh chemicals and are designed to be gentle enough for surfaces around children and pets while still cleaning effectively. However, the tablets are not for consumption and should be kept out of reach of children. Follow the directions and cautions on the product page.

The Sisal Dish Brush Refill includes the replacement sisal brush head for a compatible Plantish brush handle. The existing handle can stay in use while the worn head is removed and replaced according to the product instructions.

These are small wooden cubes designed to hold a few drops of essential oil directly on the porous wood surface. Once the scent fades, you simply add more oil rather than replacing the diffuser itself.
