Are they like beeopaks? Not really. Same function, same properties but different formulations! Much more practical for carrying around. They are made with an AD HOC MIXTURE, formulated to make the bag super performing.
3 colors, each one a different food so you don’t get confused: orange for Cheese Bag, green for Salad Bag and gray for Sandwich Bag.
The ideal is to always use the same bag for the same food so they are easily recognizable and wash less (so more environmentally friendly) and also last longer, really practical and fast solution.
