Swatch cards with a secret. Each one looks like a plain ruled card with a little frame for the ink name, until you brush ink across it and a hidden scene appears: bunnies flipping through a sketchbook, a bear at a desk with a mug, two friends sharing a journal. Every color you own gets its own tiny illustration.

• 100% cotton ink swatch cards
• 12 cards, six designs, two of each
• 2.5 x 3.5 in
• Best with fountain pen ink, water-based markers, and watercolor

Notes from The Fox: We swatched a whole shelf of ink in one sitting just to see all six pictures. That is the highest compliment we can give a swatch card.
