Who says nothing good comes out of Facebook adverts? I saw an advert for Smyle
toothpaste tabs earlier this year, ordered a trial pack, and I'm now a regular user. No plastic, easy to pack thanks to the cool glass bottle, carbon neutral shipping, and a refreshingly minty taste. You just chew a tab, wet your toothbrush, brush like normal, and you're done. I'm not going back to plastic tubes.
