Point sizes in these listings range from fine 0.7 mm tips up to a 1.6 mm bold tip; some entries are labeled simply as 'Medium' rather than giving a numeric size. Expect sizes from about 0.7 mm through 1.6 mm or labeled 'Medium.'
The selection includes ballpoint and gel inks plus thermo‑sensitive erasable gel. Some gel pens are formulated to be quick‑drying or smear‑resistant, while erasable gels offer friction‑based erasing behavior.
Erasable pens use thermo‑sensitive gel ink that erases with friction and can be affected by heat; some listings warn the ink can become colorless above certain temperatures. Vendors often recommend avoiding erasable ink for legal or official documents.
Listings use familiar descriptions like 'Fine' and 'Medium' alongside numeric measurements such as 0.7 mm and '1.6 mm bold' to indicate tip thickness and the resulting line weight.
Common comfort features include hexagonal barrels for a firmer hold, rubber or contoured grips, and in some listings a full‑length comfortable grip intended for extended writing sessions.
Some listings use renewable or reclaimed materials for pen barrels (for example, wheat‑straw), packaging printed on FSC‑certified paper with soy‑based ink, and a few mention non‑toxic ink or recycled/reclaimed materials.
