FAQs:
Q: What is a grooved workbook?
A: A grooved handwriting practice workbook is a type of notebook with pages that have indented designs. These grooves guide your pen along a path, much like a train on its tracks. This helps you improve your handwriting and strengthens muscle memory. With daily practice, you'll be able to write neatly even without the grooves, as your improved handwriting becomes second nature. Combine with the ink, making sure to improve your handwriting.
Q: How does the pen work? Will the ink disappear on whatever I write on?
A: Absolutely, it will. The special ink is made from food-grade materials, so it's safe and works like a charm. You write, and the ink disappears on its own after about 10-15 minutes, depending on the airflow and temperature of your environment. Because of this unique feature, we don't recommend using it on important documents—your signature would vanish too.
Q: How do the pen grips work?
A: The premium pen grips that come in the package have 2 ergonomic holes specifically designed to locate your child's thumb, and index finger into the correct positions, and 1 ergonomic indentation for the middle finger. Placing these three fingers properly helps develop a good writing grip.
Q: What is a glow-in-the-dark sticker?
A: The 3D-foam glow-in-the-dark sticker are made of safe materials, stick it near light source to ensure sufficient light exposure (indoor light). The sticker will absorb and store light, emitting a glow in the dark effect. The longer the exposure, the brighter and longer the glow.

This kit comes with the grooved books, pens, extra ink, and stickers. The ink does disappear after use and is easy enough to use. Changing out the ink in the pens is straightforward and simple. The ink does disappear even if the pen is used outside of the grooved area, as long as it is on the page. I didn't feel confident enough of the ink to let my little one draw elsewhere with it.If your little one has difficulties with fine motor control, this is very difficult to do. The grooves are helpful, but a shaking hand cannot stay in the grooves. It is great for little ones to use while sitting at ball games for siblings or waiting in waiting rooms.

I recently purchased the Large Magic Handwriting Practice Copybook for our daycare center, and I couldn’t be more thrilled with the results! This kit is a fantastic addition to any classroom or home-school setup.The first thing that stood out to me was the premium quality. These books are thicker with deeper grooves compared to others, making them durable enough for continuous use. Each of the 5 books is perfect for helping kiddos build key writing skills and cognitive development.What I love most about this product is the reusability. The magic disappearing ink fades, allowing the children to practice repeatedly without wasting paper! This not only promotes eco-friendliness but also provides endless learning opportunities for multiple kids at our daycare center over the years.The children have taken to it immediately, especially with the fun glow-in-the-dark stickers and well-designed pen grips. The size (larger than expected) is ideal for small hands, and the zippered pouch makes it easy to keep everything organized. It’s also incredibly safe and certified, which is a big reassurance for educators and parents.Overall, this handwriting kit has become a classroom favorite, and I can confidently say it will last through many more classes to come! Highly recommend it to any parent, teacher, or daycare looking for an engaging, reusable learning tool.

Every book is perfectly designed for handwriting practice from start to finish. Each book is plenty thick and large enough to provide a reusable surface for early learners. Uncle EJ's Reusable Copybook 5 pack with pens is everything your child needs to create excitement around writing again and again!

Letters, numbers, addition, subtraction, division and shapes are in the 5 books that you get. It comes with 2 pens that are able to fit a child's hand. 10 pen refills included. Two erasers. I'm using paper towels to remove the ink because the erasers do not remove the ink.

*****These books are even better quality than the ones I had purchased before - better printing, better materials, better games, everything is upgraded. AND this one is less expensive! I'm very impressed. They’re perfect for keeping my 4-year-old daughter occupied while I’m busy, instead of handing her the phone to scroll through TikTok. These books are a great way to entertain her —she is getting less screen time, has fun, AND is learning, really getting a heads up in life. I’d highly recommend them to other parents.*****🫶🏽
