Includes 10 Brushes. 2 Red, 2 Yellow, 2 Green, 2 Pink and 2 Orange EASY TO USE: The brushes are made of two pieces that screw together. Simply unscrew the top part, fill the blue water container with water, and tighten the top back on for the brush to be ready to paint. Make sure to empty the water out of the brushes before storing them so water does not leak out. NO MESS & ECO-FRIENDLY: Fill pens with water for clean fun. No inks or dyes are needed to paint and create colorful images when using magic water-reveal books or pads. Brushes are reusable, making them an eco-friendly option. DURABLE & SCRATCH-RESISTANT BRISTLES: Tough polyester plastic makes the brush durable enough to withstand kids' usage. Soft brush bristles paint water on smoothly and are less likely to damage painting surfaces when used gently. Make sure to use with care, as bristles can also be bent. SAFE ERGONOMIC DESIGN: Large brush pieces make it safe for kids to use without choking on the pen. Recommended for kids ages 3 and up. Chunky brush pens make it easy for small hands to hold and use. Great for helping kids practice holding pens and using fine motor skills. REUSABLE & DESIGNED TO TRAVEL: Brushes can be filled and reused. The compact size is ideal for traveling. When paired with other magic water-reveal activities, the whole experience can be had over and over again. Use KangaToys Aqua Brush books or other magic color-with-water activities for endless fun!
