The books are pretty good. There is one for the alphabet , numbers, and one for drawing.
They erase on their own... however if you rub it I have learned it erases faster.
They also have some characters I believe in Chinese in the number section which is pretty interesting.
The only problem I saw with the book is it is not how I write “1”- in this book they write it with a slant. The other letters and numbers were pretty accurate and the lines help make it easier.
Erases on its own
Plenty of ink
Easy to travel with
Doesn’t make messes
The ones are not written how they are in school.
Overall great activity for kids to practice and learn basic drawings
