This ice pack is recommended when transporting temperature vulnerable products like liquid yeast particularly in the summer months. We take parcels with yeast to the post office after 4pm.
While the parcel may not arrive still cold, it will give added protection for part of the journey.
We recommend express post (500gm express post satchel) if purchasing liquid yeast products.
Within the express post route, this will ensure overnight delivery. More remote locations may take 2 days.
