Explain. I have a mother who is losing her sight and has mild dementia. I have a tablet so she can play games and watch movements. Pleasant surprise that she likes it. But since she doesn't see that well, she smacks the tablet like she's killing flies on the table. So she goes through a lot of pen. I've seen prices averaging $9 for one online and in stores. So I scored when researching this product. Let's hope she needs more packages, which means she lives longer!
