New Toy! (Ruling Pen)

After taking Julie W.'s (wonderful!) Ruling Pens class, I got the urge to replace my current ruling pens, as they've gotten rusty (see close-up pic below). I bought them shortly after Cmas, 2019 (a post-Cmas gift to myself!) on amazon (for only $10 for all 3!)

When i browsed around again, I found another 3 pack (once more, only $10!), and this time, there was a bonus pen included (below).

I love the bigger size, and the marks it makes, however, I do not like the handle. I wish it was round instead of flat, as it's not comfortable to hold. (see vid. below)

All of my ruling pens: 

Top R corner, old set

Bottom 3 still in package, new ones.

Close up of new ones -- same as old ones.

Can you see the rust on these? They work pretty good, but for $10, why not "upgrade"?😉

Sample of pen play.
