Maybe this one has already been discussed here, sorry. Here is its link : www.librette.com
Thus it seems a Bellecup by the Librette Inc. company may have existed, and is registered as having the FDA approval.
Yet we only got the home page of the website, as none of the links are actually 'clickable'. There's not even a proper photo of the cup. And the dates at the bottom are 2008-2010..
But this one isn't to be confused with the Bellecup with a specific shape, by the Irish company Rubicon Healthcare!
