HOW
TO USE IT: Immerse
it in water so that it absorbs the liquid.
After 1 minute empty the Pierravin.
Put a bottle inside, and... Cheers !
A
guarantee of
coolness...
but how does it work ? It
is based on the principle that energy isn't lost
but transforms itself : the water which
evaporates in the stone keeps it fresh inside.
