Please try to keep your bottles in the upright position. During normal use the bottles should not leak. But the oil is meant to come out of the rollerball. We cannot be responsible for any damage due to any leaks from the bottles.
Make sure you keep the lids securely tightened. This will help the rollerball to stay in place and help prevent any leakage!
