We are completely obsessed with the ingenious idea that is the Beauty To Go Refillable Pen ($25) by Trish McEvoy. This must-have gadget twists off at the bottom, allowing you to fill with your favorite Trish McEvoy foundation cheap-o Walgreens foundation. To dispense a teeny, even amount of product, just click the pen at the bottom and your makeup will flow to the tip. So easy for traveling—we confess to ordering one for each purse.
