Review title is Keep looking if you are wanting to use as a nurse. [SEP] Doesn't stick well to disposable masks. Definetly not recommended if you need to take your mask off at any point because the adhesive doesn't work after a single use. I wish I would have researched more because there are better alternatives for nurses who have to switch masks throughout their shifts. This product would be best for someone who needs to wear a mask for a short period of time without needing to remove it.
