What you need is:
- an empty container,
NOTE: always make small amounts of this mixing medium and exchange it every two weeks since we're not adding any preservatives that would prevent it from going bad. I made a fairly large amount this time to show you how it's done.
So let's look at the price and how efficient it is. I bought 100 ml of glycerin for 5 dollars, and I can get 300 ml of mixing medium while you would pay $108 for the same amount of MAC's Mixing Medium. I love it! :)
