This model is designed for children aged 3 years and up, which is clearly indicated because it contains small parts that could pose a risk for younger children. The chunky egg shape helps little hands grip the pens more securely, reducing slips while they draw. However, you should always supervise younger kids during creative play, especially if they tend to put things in their mouths. As long as you respect the age recommendation and keep it away from under-3s, you can feel comfortable letting your child explore drawing with these pens.
