Their creator, Clementine Henrion, explains the concept behind them:
I designed the Helium Eternal concept in a reminiscence of the tender age: the childhood memory of this magnificent, brightly shining balloon you proudly bring back from the park, but which will alas tragically deflate within few days…
This early disappointment has influenced me to create a new interpretation of the children balloon: an ETERNAL one, which would fly forever and never go down again.
The shark may be my favourite, although the gold and balck striped heart is pretty darn cool too. Either way I need these in my life.
