TL;DR: Twist off the head, fill to the line with the right refill, prime the pump with 2-3 pulls, and spray. The Foaming Spray Bottle is built for Koh foaming products only.
1. Twist off the head
Turn anti-clockwise. Press down firmly as you twist if it feels tight.
2. Fill to the line
Fill to the shoulder line. That gives you the full 300 mL capacity.
3. Prime and spray
Pull the trigger 2-3 times, then spray using the foam modes.
