### ⭐⭐⭐⭐⭐ Used for my refills
*by A***R on August 30, 2025*

Great pen for refill

### ⭐ Felt tip. Not rollerball
*by �***࣪ on October 16, 2025*

These are not rollerball pens. They are felt tip pens. With felt tip pens, when you write slow the ink would get thicker on paper. When you write fast, it would be streaky.
