My 6 and 7 year olds are totally obsessed and have been texting each other secretly for days since they arrived. Children can write easily with these pens. Her handwriting is very similar to normal. The UV cap is the perfect way to keep your UV light source close and not lost. My son is even willing to practice every night before his weekly spelling test because I let him use them. I'm going to take a dozen of these to school to give to a teacher for small group classes because he writes more than usual now and I think the same magic will work on other students.
