Reposting this deal as they have more stock - https://www.ozbargain.com.au/node/625556
Seem like a pretty good deal. Someone in the previous deal who had bought them suggested that they were better quality than others but I can't really comment.
Edit: Removed reference to a possibility disposable masks can be recycled at supermarkets now.
No, you cannot recycle used face masks in the soft plastics (plastic bag) recycling bins at supermarkets.
