I would buy right away for a younger child so they could learn comfortable writing

What better way to start than with pens (bec lefties often have messy writing, which he does, but shhhhh!

I like changing up my colors on a day-to-day basis (purple today, green tomorrow, etc.).Also, I'm concerned that if I get too used to this pen, I'll have trouble transitioning back to "normal" pens, and my writing will look all messed up when I don't bring my own pen

It is not comfortable in my hand & my writing suffers

Everyone can read my writing again and no right handed person can steal it as they have trouble writing with it

I always had to spend a fortune on smudge proof pens and felt bad that his hand writing lacked due to being taught by right handed teachers and myself most of his life
