The Pen Pal 4-in-1 Makeup Pen by Alleyoop is a versatile and convenient cosmetic product, perfect for on-the-go touch-ups or travel. Kaylyn praises its compact design and functionality, with four essential makeup tools in one pen. The highlighter, lip liner, eyebrow pencil, and eyeliner can be easily accessed by clicking the desired color. The eyeliner is a smudgy charcoal shade, while the eyebrow pencil offers a pretty brunette color. The lip liner is a lovely corally mauve, and the highlighter is a champagne shade. Overall, Kaylyn loves the Pen Pal for its ease of use and suitability for natural, no-makeup makeup looks. However, no potential drawbacks are mentioned in the review.
