After trying unsuccessfully to down size my cosmetics bag, Amazon provided me with a solution. And just as an aside, for me this incident confirms that Amazon has mind reading technology! ;) I am sure that everyone has heard of the packing hack where you use contact lens cases to store small quantities of cosmetics? I don't have contacts, so without even searching, Amazon showed me ads for these tiny screw cap containers.
I have been busy filling them with creams, pastes and powders. My new cosmetics bag is tiny but contains a surprising variety of products. The shocking thing is how many cosmetics come in a big container, but the actual product will just fill one of these 5 gram containers!
