hello sweet all would like to share my thoughts on using MAC flat sac bags as organizers! after almost one year of using them.. i can say I am craAaaAAaaAAaaAzy about them!! they come as a pack of three.. they are flat and almost zero weight!! i always wanted something light yet functional before i through my stuff inside my handbag. the large one i use during vacations.. the med one.. as seen in pic.. ideal for large tubes or medicin.. the small one (i dearly love!!) i use it as a make up bag! in my work bag.. i through the med & small one while here is a greaaaaat tip: when ever i carry a small pochette.. i use the small MAC to hold my make up and hand cream and small perfume so the pochette wont get any stains.. i found these ideal for me since they dont take space.. rather just hold ur stuff and keep things organized without adding weight to ur bag.. unlike normal make up bags.. hope u enjoyed my little secret! pics coming up..
