Cars Water Coloring Cards

One swipe of water and a plain outline starts revving. Your kid fills the pen, colors across the card, and yellow monster trucks, orange flames and checkered flags turn up where there was only white a moment before.

The pack holds 10 reusable cards and one water pen, and the cards keep things moving. Some pair a word like “bike” or “truck” with a picture, some count up in rows of race cars, and others are full scenes, including a truck-filled track shouting ROAR.

It all stows in a compact fold-over cover, with the cards in a red pocket, the pen alongside and a green elastic band to keep the whole garage shut for the trip.
