Dispenses thicker 500 ml conditioners and masks in measured amounts with each press, so product comes out cleanly instead of being shaken or scooped from the bottle. Reuses across bottles as each one empties.

Which size does it fit?

The larger jar sizes of Wella and Sebastian conditioners and masks. If you've bought a liter bottle (33.8 oz) of shampoo or conditioner instead, you want the liter pump.

Is it worth $9?

If you've bought a large jar, yes — it's the difference between using it easily and digging into it with your fingers in the shower. It's reusable when you rebuy.
