Clear acrylic 2-section drawer divider/insert, purchased from The Container Store. Compatible with both medium acrylic drawers and medium short acrylic drawers. I used inside short drawer to organize lipsticks, though could be used for anything make up and non-makeup related. Dimensions: 8L x 5.75W x 1.24H Willing to work out a discount for bundling inserts with acrylic drawers in my closet.
