Very useful for my 4-year-old daughter. She enjoys tracing letters and numbers every day. The pen is smooth and reusable ink is amazing. Totally worth it

"Excellent product for preschool kids. My son improved his handwriting in just 2 weeks. The books are thick and durable. Highly recommended for parents.

"The copybooks are really nice. My daughter loves the drawing one the most. Ink could have been a bit darker, but overall very good purchase."

"This is truly a magic book. My kids write on it, and the ink fades so they can practice again. Saves money and keeps them busy."

"Very useful for preschoolers. My son is just 3.5 years old and already learning numbers easily. Good quality books, nicely printed."

"Best learning kit for kids. My nephew spends hours practicing alphabets and math. Very engaging without any mobile or TV distraction."
