Review on 📚 Reusable Handwriting Copybook Set for Kids - 4 Pack Magic Practice Copybook for Letter Writing, Calligraphy, and Hand Lettering with Pen & Aid Pen Grip - Age 2-8 by Gelin Battle

My son was having trouble writing some letters and numbers backwards and this helped a lot. The ink stays on and when it dries it actually disappears and becomes transparent so you don't even have to wipe it off. The only annoyance I have with this product is that if you lose a pen you have to order new ones as only the special pens that come with them work as the product is intended. If you run out of ink, you should also buy these special refills. That caveat aside, the product is very useful, works as described, is small enough to be carried around easily but not too small to make it difficult for a child, to use it. use properly. Highly recommended.
