We’ve been using the company’s water-based, all-natural polish on our little’s fingers for a while. So we were tickled two shades of pink, red, blue, and purple to discover the worry-free formula available as nail pens. Once the polish gets flowing through the felt tip, the pens are easier to handle than a brush — especially on tiny nails.

Available online at piggypaint.com, $9.
