anyone tried storing breastmilk with daiso Styrofoam box with ice pack inside? will it be lasting than using cooler bag or cooler bag is better? in dilemma...

if u r using it to tranport breastmilk only , this is ok i guess. get more ice gel pack from daiso . But if u r using it to store milk and bring it to places instead of placing into chiller within a short period of time, consider fridge to go .
