We generally recommend using our 250 ml AVA & MAY soap dispenser as it makes mixing your hand soap super easy. However, you can also use your own dispenser. It is important that you ensure the correct mixing ratio (15g of soap to 185ml of water) and that there is still some air left in the bottle so that you can shake it well. We also offer sets without our dispenser and you can put together your favourite combinations and several sachets with the same fragrance using our Powdered Soaps Mix & Match.
