Hi Sim,
I would never get mad at you
. I am sorry, by the "sea kelp bioferment", i meant i used an old jar that used to hold sea kelp bioferment (it's a skin product i use). you can use any old skin cream jar as long as it is water and air tight. the regular jars that MMU comes in isn't water or airtight (meaning air and water cannot get into the jar), so the whipped foundation may dry out. it doesn't matter if the jar is transparent of not. i hope that helps, let me know if you need anything else.
