Wearingeul Modular Glass Pen Nib Refill Set

Seems like a great idea...

I've used expensive glass pens before and eventually the tip breaks and there goes a costly pen. This writes well and I love the idea of replaceable nibs. I haven't had a chance to use it much but so far so good.

The modular glass pen is a great writer.

The modular glass pen is a much better writer than all of my previous glass pens. I will use it to actually write, and not just demonstrate inks.

Extra Nibs are a bonus

Having extra nibs is great for me because I won't worry so much about breaking one and not having a replacement.
