It’s very quick and easy in 4 steps:
1. Remove the spray head from your perfume or aftershave bottle.
2. Remove the clear bottle from inside the OneNine5 refillable fragrance bottle.
3. Position the bottom of the clear inner bottle over the opening of your aftershave/ perfume bottle and pump down.
4. Repeat this process until you can see that the 5ml clear bottle is full.
