This Kingart pen line has the nylons tips, which means it’s synthetic instead of plastic material, which I think is often better.

KINGART™ Real Brush Pens, Set of 48 Unique Colors
The Studio twin-tip markers are perfect for beginning and aspiring artists looking to hone their techniques. The extra long flexible nylon tips are great for creating both fine lines and broad strokes in a smooth flow of water-based ink that is odorless, acid-free, and non-toxic. The chisel tip provides the edge and are used for bold lines for maximum impact when artists want dark, bold pen strokes.
