Compartmentalisation is not only a term of psychology, but also a perfect method for organizing stuff. In my case, I’ll get a few boxes to store the different types of face masks in. I’ll order holographic stickers to make them a bit prettier as well.
I’ll put all of my sheet masks in one box. Single packs in another, and then the tubs separately. In each box, I’ll put them according to the effect they have. That way I can easily choose what type of face mask to use, and also the effect I’m after.
