This is a great, thorough writing practice and learning set! My preschooler and kindergartener are both loving using these materials.
This set includes a zippered carrying case that is both fun and convenient to keep everything together. There are 4 different books that have sturdy, thick pages with different categories of writing practice in each, which is great for catering to different ages and levels of learning. There are 4 pens, each with a snap-on cap and a squishy finger placement trainer piece that can be put on or taken off the pen, plus a few dozen pen refills.
When the set arrives, the pens do not have an ink filler in them but they are super easy to load- just unscrew the tip of the pen, drop an ink refill inside, and screw the tip of the pen back on.
The actual functionality of the books for writing practice is great. The grooves are just deep enough to help guide the pen as you write, especially for learners who already have a bit of writing practice and can use the pen gently so it glides through the grooves smoothly. The pen marks disappear within a minute or 2 and are gone by the time my child is a couple of lines down so the pages can be reused very quickly.
Overall, I am really excited to use this set with my learners for a long time to come. It is already a great learning asset in our homeschool arsenal and is helping my youngest learners gain confidence and proficiency in their writing skills.
