Saw these in Boots so thought I'd give them a try. £4.99 for 8 - like Mooncups etc but disposable.
However, I've never even tried a Mooncup so no idea what they're like. You can wear them for up to 12 hrs and apparently you can even have sex while wearing one 
Any reports? Are they quite new? I was eyeing up Mooncups in Boots a few mths ago and don't remember seeing them. I've just done a search on here too and nothing's come up.
