1. Sterilize the cup
Before the first use, sterilize the cup in boiling water for 3-5 minutes.
2. Fold and insert the folded cup
There are many ways to fold the cup, we recommend the Punch Down fold and the C-fold. Once the entire cup is inside of you, simply let it pop open.
3. Check if the cup is unfolded
Reach in and feel around the base of the cup it should feel round or oval and not have any noticeable folds. If you feel any dents, gently grip the base of the cup (not the stem) and rotate it to make it unfold.
