How do I separate the inner press from the outer [re]fill?

Use a twisting motion to help facilitate separation. If the INNER PRESS feels stuck, grab the LOOP CAP and twist clock-wise while pulling apart. This will unhinge and release the INNER PRESS.

When your GRAYL is completely dry, the INNER PRESS and OUTER [RE]FILL may require more force to separate. Make sure to twist as you pull apart.
