Delta Bio 16 Customer Comments"I rarely buy 2 pens of the same brand but Gravitas is the one brand that changed my mind. I got this because I loved my dinkey and wanted to get a full pen. The pen feels premium and feels good in hand. The nib is super smooth and instantly notice that it has been well tuned. I have used it for long writing sessions and I am so pleased with it.
