Tami tried the Wing Eyeliner Pen & Stamp -2 pcs by KAJA after hearing rave reviews on Flip. The product comes with an eyeliner pen labeled for left and right use. Tami used the right pen and found it easy to apply with the help of a mirror. The stamp created a perfect wing, making her previous attempts at winged eyeliner look amateurish. Overall, Tami was impressed with the product and its ability to create a flawless winged look. However, it is unclear if the product is suitable for beginners or those who struggle with eyeliner application without the stamp.
